The volume strength of 1.5 N H2O2 solution is (AIPMT 1997)

Normality (N) = 1.5 We known that equivalent weight of H2O2 is 17 and strength of H2O2 = Normality xEquivalent weight 1.5 17 25.5 x 2 2 2 2 2 34 68g 22.4L 2H O 2H O O x -> Since 68 grams of H2O2 will produce 22.4 25.5 8.4litreof oxygen. 68 x Thus, volume strength of given H2O2 solution is 8.4.
