A mixture contains equal volumes of 0.IM KCN and 0.05M HCl solutions.

1.	A mixture contains equal volumes of 0.IM KCN and 0.05M HCl solutions. Can it act as buffer ?Why?
Answer» Solution :The MIXTURE acts as a buffer. COMBINATION of KCN with HCl, HCN is produced KCN + HCl `to` KCl + HCN Milliequivalents of HCN is 0.05 V. Milliequivalents of KCN is (0.1V-0.05V =) 0.05V. The solution contains EQUAL quantities of weak acid HCN and its conjugate base CN. Hence the GIVEN mixture is an acidic buffer solution.
