QAIPM-2000-Ph-2995: NEET 2000 Chemistry - Class 11 AIPM-2000-Ph-2995 Solution: Which statement is wrong about pH and \(H^+\)?

Which statement is wrong about pH and H+H^+?

Multiple Choice Options

  • A pH of neutral water is not zero.
  • B Adding 1 N solution of CH3COOHCH_3COOH and 1 N solution of NaOH, pH will be seven.
  • C [H+H^+] of dilute and hot H2SO4H_2SO_4 is more than concentrated and cold H2SO4H_2SO_4
  • D Mixing solution of CH3COOHCH_3COOH and HCl. pH will be less than 7.

Step-by-Step Verified Solution

CH 3 COOH is weak acid while NaOH is strong base, so one equivalent of NaOH can not be neutralized with one equivalent of CH 3 COOH. 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 + .
