Why is the pH of the first equivalence point, of a titration of polyprotic acid, not equal to7?
A titration of phosphoric acid with sodium hydroxide. The first equivalence point has a pH of about 5.
My thoughts are that because it is only the first equivalence point, only one H+ has been pulled away from the polyprotic acid, therefore the acid hasn't been fully neutralized leaving the solution more acidic.
Am I on the right track or am I missing something?
