welcome to Scaling UP! the podcast for
water traders by water treaters where

0:12.7

0:17.0

we’re Scaling UP! on knowledge so we
don’t Scaling UP! our systems

0:17.0

0:23.0

hello Scaling UP! nation Trace Blackmore
here your host for Scaling UP! h2o and

0:23.0

0:31.0

folks once again another episode from
questions from the Scaling UP! nation

0:31.0

0:37.2

thank you so much nation for riding in
or letting me know directly what

0:37.2

0:43.8

questions you had and that way I know
what shows to bring you without that

0:43.8

0:48.7

information you would be listening to
silence right now maybe you would prefer

0:48.7

0:54.9

that but I’m betting you probably would
not so keep those questions coming you

0:54.9

0:59.2

might be wondering how do I get those
questions to you trace well I’m so glad

0:59.2

1:04.1

you asked it’s very easy
you’re gonna go to https://scalinguph2o.com

1:04.1

1:09.8

and you have two ways to get your
questions to me one is you can go to the

1:09.8

1:15.9

show ideas page and write in your
question or two you can record your

1:15.9

1:23.2

voice asking me the question and I will
get your question answered on the air

1:23.2

1:29.2

and if I use your voice on the air I
will send you the most amazing Scaling

1:29.2

1:34.2

UP! t-shirt you will be the envy of all
your friends and you can get that by

1:34.2

1:40.0

sending me your questions via voice mail
we’re not too long ago I did a show on

1:40.0

1:46.6

calibration of meters and the questions
I had were either around how the meters

1:46.6

1:54.5

work or what pH actually was and folks I
don’t know what it is but more often

1:54.5

2:00.8

than not people like myself that teach
water treatment make water treatment

2:00.8

2:06.5

needlessly overcomplicated so the people
that are trying to get the information

2:06.5

2:12.4

don’t truly understand the why behind
the question that they are asking I

2:12.4

2:18.3

don’t know why that is and not everybody
does that but more often than not when a

2:18.3

2:23.7

water Treaty Act a water treaty
question the water treater that’s

2:23.7

2:30.2

answering answers with the intent of the
other person to know how smart they are

2:30.2

2:35.2

well folks out there in the Scaling UP!
nation you know I’m a dumb guy and I

2:35.2

2:39.6

don’t mind that people know that I’ve
said it on the air I’ve got 10,000

2:39.6

2:46.0

listeners there it is it’s out there so
with that being off the table I just

2:46.0

2:52.2

want you to understand the information
that you need to know in order to be a

2:52.2

2:57.1

better water trigger and I receive
several questions as I alluded to

2:57.1

3:03.2

earlier around the pH meter itself but
then also pH so what I’m going to do in

3:03.2

3:12.5

today’s episode is explain pH in a way
that will make sense so if you were to

3:12.5

3:20.7

look at pH what the heck is it and I was
in a class once when somebody asked what

3:20.7

3:27.2

is pH and the answer was the anti log of
the hydrogen ion concentration and that

3:27.2

3:31.5

was it that was the answer and by the
way the person that was asking that

3:31.5

3:37.5

question had been in the water treatment
industry for about two weeks so again we

3:37.5

3:42.6

don’t have to overcomplicate things we
need to make sure we understand the

3:42.6

3:48.8

information that we need to know now
truth be known that was a perfect way to

3:48.8

3:55.9

answer that question but it wasn’t what
that person needed to hear now I bet if

3:55.9

4:01.0

you told him that now based on him being
in the water treatment industry for

4:01.0

4:05.6

seven plus years I’m sure he would say
hey that makes a lot of sense but at

4:05.6

4:08.6

that moment in time that’s not what he
needed to hear

4:08.6

4:16.2

here is how I like to explain pH now I
need you in your mind’s eye to visualize

4:16.2

4:24.1

the pH scale and we have a line starting
from zero going all the way up to 14

4:24.1

4:29.8

with seven being in the middle now most
of you out there on the Scaling UP!

4:29.8

4:36.7

nation know that seven is
neutral when it comes to pH a lot of us

4:36.7

4:41.6

don’t know what that means as neutral so
I’m going to explain that for you so

4:41.6

4:45.9

again you have to have this visual in
your head where you’re going from zero

4:45.9

4:56.0

all the way up to 14 with seven in the
middle now water is h2o two parts of

4:56.0

5:02.7

hydrogen one part of oxygen we’re now
going to rewrite this and if you’ve had

5:02.7

5:09.6

organic chemistry you always write water
as H o H it’s the exact same molecule

5:09.6

5:14.9

we’re just writing that a little bit
differently so here’s what I want you to

5:14.9

5:21.2

visualize that long line that has zero
on one end and 14 on the other end with

5:21.2

5:29.3

seven in the middle and then right above
seven you’ve got H o H now this is what

5:29.3

5:35.2

that means and this is what we mean when
we say neutral when you have a pH of

5:35.2

5:43.0

seven it means you have equal parts of
hydrogen ions and hydroxyl ions now

5:43.0

5:50.1

hydrogen’s the H hydroxyls are the OHA
ends are the positively charged o eights

5:50.1

5:54.8

are the negatively charged and we have
equal parts of them at seven now we

5:54.8

6:02.3

might have 20 billion H’s at seven but
that means we have 20 billion o H’s at

6:02.3

6:09.8

seven so that’s what we mean when we say
that it’s neutral and of course water is

6:09.8

6:15.2

neutral because it’s just hydrogen and
hydroxyls and we have equal parts of

6:15.2

6:22.0

them now let’s explain pH based on that
now we’re going to start moving further

6:22.0

6:28.2

and further away from seven down to the
one and we all say well hey the lower

6:28.2

6:35.3

the number is in pH the more acidic it
is well here’s why that is the further

6:35.3

6:43.4

you move closer to one or away from
seven the more hydrogen’s you have

6:43.4

6:50.2

in the sample hydrogen sometimes called
the proton that is what acid is derived

6:50.2

6:58.5

from and the more you have of hydrogen
the more acidic it is now so much when

6:58.5

7:04.2

you get all the way to the end of the pH
scale all you have is hydrogen and that

7:04.2

7:09.1

gets into some of the super assets that
we have in chemistry now let’s look at

7:09.1

7:15.6

the other side of that the further we
move up the pH scale so away from seven

7:15.6

7:21.7

but moving towards fourteen the more
basic or the more caustic those are

7:21.7

7:29.2

similar terms the sample gets the more
Oh H concentration we have in the sample

7:29.2

7:35.0

if you start looking at your bases you
will see that they are all made out of O

7:35.0

7:42.4

HS so if you get all the way up to the
14 range again those are super caustics

7:42.4

7:51.8

in chemistry and all you have are OHS at
that range so that is what pH is

7:51.8

8:01.0

measuring it’s measuring how much or how
little hydrogen is in the sample so the

8:01.0

8:07.2

lower we go the more hydrogen we have in
the sample the higher we go the less

8:07.2

8:13.4

hydrogen or more hydroxyl we have in the
sample and then that’s where we get pH

8:13.4

8:18.9

from that being said I heard someone
answered the anti log of the hydrogen

8:18.9

8:25.1

ion concentration again a perfectly
acceptable answer but not until we got

8:25.1

8:30.9

some more information so it said the log
of the hydrogen ion concentration well

8:30.9

8:37.6

log is just a big fancy way for us to
say times 10 its times 10 of the

8:37.6

8:44.3

hydrogen ion concentration so at 7
remember I have equal parts of

8:44.3

8:53.2

hydrogen’s and equal parts of hydroxyls
well now if I go from 7 to 6 I have 10

8:53.2

9:00.3

times more hydrogen’s at 6
then I did at 7:00 if I move down to

9:00.3

9:09.3

five I have 100 times more hydrogen’s at
five than I did at seven and I keep

9:09.3

9:15.0

multiplying that number by ten until I
get all the way down to a million which

9:15.0

9:20.6

means there’s just all hydrogen’s in
that sample well let’s start at seven

9:20.6

9:25.9

and go the other way so if I start at
seven and go to eight I have 10 times

9:25.9

9:34.2

less hydrogen ions than I did at seven
if I went up to nine I have a hundred

9:34.2

9:42.0

times less hydrogen ions that I did at
seven remember pH is a measure of the

9:42.0

9:48.4

hydrogen in the sample but we can also
look at it because we know what pH is

9:48.4

9:53.4

telling us now that when I go from seven
to eight even though there’s 10 less

9:53.4

10:01.3

hydrogen’s or in the sample I have 10
more hydroxyls in the sample remember

10:01.3

10:06.3

that’s the OHS and then if I move to
eight I have a hundred times more

10:06.3

10:12.0

hydroxyls in the sample all the way up
when I get to 14 it’s a million hits all

10:12.0

10:18.7

hydroxyls so I hope you can visualize
that because if you can understand that

10:18.7

10:26.9

that is what is going on with pH and so
many people will look at a sample and

10:26.9

10:31.1

maybe they’re cleaning the system with
acid and it’s supposed to be at four and

10:31.1

10:36.1

they see it at two and they say oh well
that’s no big deal it’s only three

10:36.1

10:42.4

numbers off well that’s a huge deal
that’s a thousand numbers off there’s so

10:42.4

10:48.1

much free hydrogen in that sample
whatever you’re doing you’ve got a

10:48.1

10:53.7

thousand times more than what you were
told that you need and sometimes that

10:53.7

11:00.3

cannot be a good thing so that’s what pH
is now when you press pH on your meter

11:00.3

11:06.7

what your meter is doing it’s measuring
how much hydrogen’s in that sample and

11:06.7

11:13.1

then this is where we get the seven from
if we were to look at the decimal points

11:13.1

11:20.9

of all of the graduations of pH zero all
the way up to 14 when we’re at the zero

11:20.9

11:27.7

it’s a 1 everything in there is hydrogen
when we get to 1 it’s going to be zero

11:27.7

11:36.4

point one two is zero point zero one
notice one decimal point four one two

11:36.4

11:44.0

decimal points 4 2 all the way up to 14
decimal points at the very end of the

11:44.0

11:50.8

scale so that’s where we get that pH
range of 0 to 14 and what’s in the

11:50.8

11:56.9

middle of that will that’s 7 and now you
know that a pH of 7 is equal parts of

11:56.9

12:05.2

hydrogen and equal parts of hydroxyl
folks I hope that helps you understand a

12:05.2

12:11.8

lot more than when I take a pH reading
I’m simply jotting down a number you now

12:11.8

12:18.7

know what that means now all of the
products that we use are based on that

12:18.7

12:24.0

range of pH in which they work the best
end and then that’s why it’s so

12:24.0

12:29.1

important that we are staying within
whatever ranges your company says that

12:29.1

12:34.6

that particular product has to stay in
that range if you have ever taken my

12:34.6

12:40.3

course at aw T’s technical training you
know that I talked about one of the five

12:40.3

12:46.4

ingredients of scale is pH if you’re
wondering it’s calcium hardness its

12:46.4

12:52.0

alkalinity its pH its temperature and
then all the dissolved solids in the

12:52.0

12:59.4

water well as we increase pH the more
susceptible to scaling we become as we

12:59.4

13:06.4

reduce pH the more susceptible to
dissolving scale the water becomes so

13:06.4

13:11.4

again I hope that this helps you
understand pH and I want to thank

13:11.4

13:16.9

everybody out there that ask me
questions around pH and I sincerely hope

13:16.9

13:20.5

that this hell
