Ph Of Salt

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.

Importance of pH|Salts

Example briefly about the pH values of salts.

pH of a salt of a strong base with weak acid

pH of a salt of a strong base with weak acid

What is the pH of a salt which was produced by a strong acid and a strong base ?

Give an example of a salt solution whose pH is independent of salt concentration.
