Question

100 mL of an $H_2O_2$ solution was diluted to 400 mL. 20 mL of this diluted solution required 10 mL of 0.1 M $KMnO_4$ solution in an acidic medium for complete oxidation. What is the "volume strength" of the original $H_2O_2$ solution?

Correct answer: D. Milli-equivalents of meq. Thus, 20 mL of diluted contains 5 meq. Normality of diluted . The solution was diluted from 100 mL to 400 mL (dilution factor of 4), so the original normality = . Volume strength = .
