Which of the following statements are wrong?

Options

A. pH of neutral water is always 7.0
B. When a base is titrated against an acid, the pH at the end point is 7.0
C. Lesser is the pH than 7, more acidic is the solution and higher the pH than 7, less basic is the solution
D. AgCl is more soluble in `NH_(3) ` than in water.

Answer

A, B, C

Explanation

(a) is wrong because PH of neutral water depends upon temperature
(b) is wrong because at the end point, pH depends upon the nature of acid and base being titrated
(c) is wrong because higher the pH than 7, more basic is the solution
(d) is correct because AgCl dissolves in `NH_(3) ` to form a soluble complex.
