So they tell sodium bicarbonate is the sodium sart of carbonic acid and it has a pgay of 6 .37.
00:10
And we wanted to determine which of the substances that we had in problem 2 .4 will react significantly with sodium bicarbonate.
00:20
So what that is really asking us is if we were to do this acid -based reaction, which of these would go from a lower, p .k .a.
00:33
To a higher pkk, because this would just be an acid -base reaction with sodium bicarbonate.
00:41
And the way i remember this is with a little jingle, low to high, it will fly high to low, it won't go.
00:49
So let's just compare.
00:51
So on this side, we have 6 .37.
00:57
So let's see, which of these is going to be lower than that? well, 19 .3 is higher, so acetone doesn't work...
