A) \[0.8\,M\,{{H}_{2}}\,S+0.8\,M\,KH{{S}_{+}}\]
B) \[2M{{C}_{6}}{{H}_{5}}N{{H}_{2}}+2M{{C}_{6}}{{H}_{5}}N\,{{H}_{3}}B{{r}^{-}}\]
C) \[3M{{H}_{2}}C{{O}_{3}}+3MKHC{{O}_{3}}\]
D) \[0.05\,M\,KCl{{O}_{4}}+0.05\,M\,HCl{{O}_{4}}\]
Correct Answer: D
Solution :
[d] 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 used is \[HCl{{O}_{4}}\] which is strong acid and \[KCl{{O}_{4}}\] is salt of this acid with strong base. So it is not an example of buffer solution.
