What will the pH of the solution of the salt of weak acid and weak base? (K_(b) = 1 xx 10^(-6) and K_(a) = 1 xx 10^(-4) )

pH of a salt solution of weak acid (pK_(a) = 4) & weak base (pK_(b) = 5) at 25^(@)C is :

Statement-1: Aqueous solution of ammonium carbonate is basic. Statement-2: Acidic/basic nature of a salt solution of a salt of weak acid and weak base depends on K_(a) and K_(b) value of the acid and the base forming it.

Calculate the hydrolysis constant of a salt of week acid (K_(a) = 2 xx 10^(-6)) and of a weak base (K_(b) = 5 xx 10^(-7))

K_(h) of salt obtained from strong acid and weak base is 2 xx 10^(-5) . The K_(b) of weak base is

pH of 0.05 aqueous solution of weak acid HA (K_a=4×10^(-4)) is
