Answer #1

Buffer solution: Buffer solution is a mixture of weak acid/weak base and its salt with strong base/strong acid.

KCN/HCN ==> acts as a buffer solution. It is an acidic buffer combination.

Na2SO4/NaHSO4 ==> acts as a buffer solution. It is an acidic buffer combination.

NH3/NH4NO3 ==> acts as a buffer solution. It is a basic buffer combination.
