Which statement is wrong about pH and H + ?

Adding 1 N solution of CH 3 COOH and 1 N solution of NaOH, pH will be seven.

pH of neutral water is not zero.

[H + ] of dilute and hot H 2 SO 4 is more than concentrated and cold H 2 SO 4

Mixing solution of CH 3 COOH and HCl. pH will be less than 7.

Correct answer: B

CH₃COOH is weak acid while NaOH is strong base, so one equivalent of NaOH can not be neutralized with one equivalent of CH₃COOH. Hence the solution of one equivalent of each does not have pH value as 7. Its pH will be towards basic side as NaOH is a strong base hence conc. of OH^– will be more than the conc. of H⁺.
