MCQ
Which one of the following is not a buffer solution
- A$0.8\,M\,{H_2}S + 0.8\,M\,KHS$
- B$2\,M\,{C_6}{H_5}N{H_2} + 2M\,{C_6}{H_5}\mathop N\limits^ + {H_3}\,Br$
- C$3\,M\,{H_2}C{O_3} + 3\,M\,KHC{O_3}$
- ✓$0.05\,M\,KCl{O_4} + 0.05\,M\,HCl{O_4}$
✓
Answer
Correct option: D.
$0.05\,M\,KCl{O_4} + 0.05\,M\,HCl{O_4}$
(d) Because $HCl{O_4}$ is a strong acid. While buffer is a mixture of weak acid and their salt.
