it’s good start isn’t it now I want to
it’s good start isn’t it now I want to start this talk by taking a look at the
start this talk by taking a look at the
start this talk by taking a look at the glass of water in front of you you got
glass of water in front of you you got
glass of water in front of you you got one glass of water bottle of water
one glass of water bottle of water
one glass of water bottle of water whatever it is just taking your hand and
whatever it is just taking your hand and
whatever it is just taking your hand and look at it up close and just tell me
look at it up close and just tell me
look at it up close and just tell me what you see
what you see
what you see it’s colorless still bit featureless to
it’s colorless still bit featureless to
it’s colorless still bit featureless to be honest boring maybe is the word
be honest boring maybe is the word
be honest boring maybe is the word you’re using in your head right now so
you’re using in your head right now so
you’re using in your head right now so what on earth are we going to talk about
what on earth are we going to talk about
what on earth are we going to talk about for the next 15 minutes well as it
for the next 15 minutes well as it
for the next 15 minutes well as it happens boring things are things that I
happens boring things are things that I
happens boring things are things that I get interested in sometimes and in
get interested in sometimes and in
get interested in sometimes and in moments of idle speculation I think
moments of idle speculation I think
moments of idle speculation I think about them years and years and years ago
about them years and years and years ago
about them years and years and years ago in one of these idle moments of
in one of these idle moments of
in one of these idle moments of speculation I was thinking about water
speculation I was thinking about water
speculation I was thinking about water in the context of this this is the pH
in the context of this this is the pH
in the context of this this is the pH scale so over there pH 1 acids pH 14
scale so over there pH 1 acids pH 14
scale so over there pH 1 acids pH 14 alkali and I was thinking to myself the
alkali and I was thinking to myself the
alkali and I was thinking to myself the the only thing I can think of that’s pH
the only thing I can think of that’s pH
the only thing I can think of that’s pH 7 neutral neither acid nor alkaline is
7 neutral neither acid nor alkaline is
7 neutral neither acid nor alkaline is water and now you know started to think
water and now you know started to think
water and now you know started to think about that I thought oh of course that
about that I thought oh of course that
about that I thought oh of course that makes sense because an acid is just
makes sense because an acid is just
makes sense because an acid is just defined as something that sir has a
defined as something that sir has a
defined as something that sir has a concentration of H+ ions hydrogen nuclei
concentration of H+ ions hydrogen nuclei
concentration of H+ ions hydrogen nuclei and the more you have of them the
and the more you have of them the
and the more you have of them the further the lower the pH the more Oh H
further the lower the pH the more Oh H
further the lower the pH the more Oh H minus ions you have in solution in
minus ions you have in solution in
minus ions you have in solution in something hydroxide you get higher in
something hydroxide you get higher in
something hydroxide you get higher in the pH scale so sodium hydroxide drain
the pH scale so sodium hydroxide drain
the pH scale so sodium hydroxide drain cleaner is 14 pH 14 and that is an
cleaner is 14 pH 14 and that is an
cleaner is 14 pH 14 and that is an alkali the only thing that has an equal
alkali the only thing that has an equal
alkali the only thing that has an equal number of H+ and OH h minus ions is h o
number of H+ and OH h minus ions is h o
number of H+ and OH h minus ions is h o h which is water obvious
