The equivalence point during titration of an acid with a base may not occur at a pH of 7.0 because
1. A solution containing a weak acid or a weak base could never be neutral.
2. hydrolysis of the salt produced may make the solution acidic or basic.
3. the indicator may be one that changes color at some other pH.
4. if a strong acid or base is used, it is completely ionized and therefore not neutral.
5. The statement is false; the pH must be 7.0 at the equivalence point.
