Is it possible for the equivalence point of a titration to not be at pH 7?
Yes, in fact, it most often is not.
Besides the trivial examples of non-acid-base titrations, the equivalence point of an acid-base titration is the point where there is only the salt and water in solution, therefore its
When it's a strong acid - strong base titration such as
(Sodium Hydroxide - Hydrochloric acid titration)
The remaining salt is made of an extremely weak acid (
However, if we do a strong acid - weak base or strong base - weak acid titration, the remaining salt can change the pH. For example:
(Sodium Hydroxide - Acetic acid titration, used - for example - to analyze vinegar)
The pH of sodium acetate will only be 7 in minute enough quantities.
