1.	K_a for a weak monobasic acid HA is 1 xx 10^(-4). Calculate (a) hydrolysis constant of KA and (b) neutralisation constant for the reaction of HA with KOH.
Answer» Solution :HYDROLYSIS constant `(K_b)` is given as, `K_h=(k_w)/(k_a) = (1 xx 10^(-14))/( 1 xx 10^(-4)) = 1 xx 10 ^(-10)`NEUTRALISATION constant `(K_a)` for the reaction of HA with KOH is given as, `K_n=K_(H)^(-1) =1 xx 10^(10)`
