Question
Which one of the following is NOT a buffer solution?
Options
A.0.8 M H2S + 0.8 M KHS
B.2MC6H2NH2 + 2MC6H2NH2Br-
C.2MH2CO3 + 3MKHCO3
D.0.05M K CIO4 + 0.05M H CIO4
Solution
Buffer solution contains weak base = salt of weak base with strong acid or weak acid+ salt of weak acid with strong base.
In option (d) the acid with used is HClO4 which is strong base . So it is not an example of buffer solution.
