What is the volume (in \(\mathrm{mL}\) ) of \(20 \mathrm{vol} \mathrm{H}_2 \mathrm{O}_2\) required to completely react with \(500 \mathrm{~mL}\) of \(0.02 \mathrm{M}\) acidified \(\mathrm{KMnO}_4\) solution?
- A 14
- B 7
- C 28
- D 42
Answer & Solution
Correct Answer
(A) 14
Step-by-step Solution
Detailed explanation
Given, Volume of acidified \(\mathrm{KMnO}_4\) solution \(=500 \mathrm{~mL}\) Molarity of acidified \(\mathrm{KMnO}_4\) solution \(=0.02 \mathrm{M}\) Volume strength of \(\mathrm{H}_2 \mathrm{O}_2=20 \mathrm{vol}\) \(\because \quad\) Normality…
