Explanation / Answer

answer :b. pH will be greater than 7 at the equivalence point.

explanation:

weak acid and strong base both are consumed at equivalence point . only salt is formed . this salt is having basic nature due to strong base is dominent

CH3COOH weak acid

NaOH strong base

CH3COOH + NaOH ---------------> CH3COONa + H2O

CH3COONa only remains

on hydrolysis of this salt will give OH-

CH3COO- + H2O ---------------->CH3COOH + OH-

so it is basic .

pH of this salt with concentration C

pH = 7 + 1/2 [pKa + logC]
