Question

Which of the following solutions is a good buffer system?

Answer 1

Answer #1

Buffer solution is a mixture of weak acid and its conjugate base formed with strong acid.

Or weak base and it's conjugate acid formed with strong acid

Hence among the given, option D . It is a mixture of weak acid (HCN) and it's conjugate base NaCN.

Option A has both strong acid (HNO3) strong base NaOH.

B ha strong acid HNO3 & strong base LiOH.

D has both are strong.
