In the titration of acetic acid versus sodium hydroxide , the pH of the solution at equivalence point (whene temperature is `25^(@)C ) ` is :

A

about 5.5

B

about 6.5

C

about 7

D

about 8.5

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_3COOH ` is weak acid , NaOH is strong base. ` CH_3COONa` undergoes anionic hydrolysis hence basic solution.
