The pH of an acetic acid + sodium acetate buffer is given by pH = pK_(a) + log . "[Salt]"/"[Acid]" " where " K_(a) of acetic acid = 1.8 xx 10^(-5) If [Salt] = [Acid] = 0.1 M, then the pH of the solution would be about

Hydrolysis constants of two salts KA and KB of weak acids HA and HB are 10^(-8) and 10^(-6) . If the dissociation constant of third acid HC is 10^(-2) . The order of acidic strengths of three acids will be :

The solubility of a salt of weak acid (AB) at pH 3 is Y xx 10^(-3) " mol "L^(-1) . The value of Y is ____. (Given that the value of solubility product of AB (K_(sp))=2xx10^(-10) and the value of ionization constant of HB (K_(a))=1xx10^(-8) )
