Barbituric acid, H-Bar, was discovered by Adolph von Baeyer (of Baeyer aspirin fame) and named after a friend, Barbara. It is the parent compound of widely used sleeping drugs, the barbiturates. Its pKa is 4.01. What will be the [H+] and pH of a 0.050 M solution of H-Bar?
For the question above, on the K expression, do you include the A-?
So, for example [H+][Bar-]/[H-Bar]?
Normally it's like [CNO-][H+]/[HCNO], so I was wondering if you would include the thing you add to H+ to make the acid in the k expression if it's not given.
