Solution
The correct option is A Statement 1 is true , statement 2 is true ,statement 2 is a correct explanation of statement 1 For a salt of weak acid and weak base, degree of hydrolysis h=√Kh. Here, Kh is the hydrolysis constant. Thus the degree of hydrolysis is independent of concentration.
Hence, when the aqueous solution of ammonium acetate is diluted, then its degree of hydrolysis does not change.
