1.	Assertion (A) :P^(H)of an aqueous solution of acetic acid remians unchanged on the addition of sodiumacetate. Reason ( R ) : Dissociation of acetic acid is supressed by the addition of soidum acetate due to commonion effect.
Answer» Both (A ) and (R ) are true and (R )is the CORRECT explanation of (A ) Both (A) and (R ) are true and (R )is not the correct explanation of (A) (A ) is true but (R ) is false (A ) is false but (R ) is true Solution :Common ION EFFECT decreases DISSOCIATION
