Match Column -I with Column -II `:`
Column -I Column-II
(A) Ph of water ( p ) `( 1)/( 2) p K_(w)`
( B ) Ph of a salt of strong acid and strong base ( q) `pH = (1)/(2) [ pK_(w) + pK_(a) + log c ]`
(C ) Ph of a salt of weak acid and strong base ( r ) `pH = ( 1)/( 2) [ pK _(w) + pK_(a) - pK_(b)]`
(D) Ph of a salt of weak acid and weak base (s) 7
where `K_(a) , K_(b)` are dissociation constants of weak acid and weak base and `K_(w) = ` Ionic product of water.
