Assertion : Buffer solutions are those which resist change in pH value on the addition of a small amount of acid or a base to it. Reason: Mixture of NH_4OH and NH_4 Cl acts as basic buffer.

Silver chloride dissolves in excess of NH_4OH . The cation present in solution is.

Assertion :- Degree of hydrolysis and pH of a WAWB salt is independent of initial concentration of salt. Reason :- The solution of NH_(4)CN in water has pH slightly greater than ?

Asseration : A solution containing a mixture of acetic acid and sodium acetate maintains a constant value of ph on addition of small amounts of acid or alkali. Reason : A solution containing a mixture of acetic acid and sodium acetate acts as a buffer solution around ph 4.75.

Assertion (A ) : A buffer solution has a capacity to resist the change in pH value on addition is small amount of acid or base to it. Reason (R ) : An aqueous solution of ammonium acetate can act as a buffer.

Assertion: The pH of NH_(4)OH remains unchanged on addition of NH_(4)Cl . Reason : Addition of NH_(4)Cl suppresses the dissociation of NH_(4)OH due to common ion effect.
