NEET Chemistry Hydrogen Questions Solved


Find the volume strength of 1.6 N H2O2 solution.

(A) 8.96                               

(B) 2.16

(C) 9.16                               

(D) 5.14

(A). We know that strength = Normality × Eq. wt. and Eq. wt. of H2O2 = 17

         Strength of 1.6 N H2O2 solution = 1.6 × 17 g/l

       Now 68g of H2O2 gives 22400 ml O2 at N.T.P.

          1.6 × 17 g of H2O2 will give

           2240068×1.6×1.7=8960 ml of O2 at N.T.P.

       But 1.6 × 17 g of H2O2 are present in 1000 ml of H2O2 solution.

       Hence 1000 ml of H2O2 solution gives 8960 ml of O2 at N.T.P.

       1 ml of H2O2 solution will give =89601000=8.96 ml of O2 at N.T.P.

        Hence the volume strength of 1.6N H2O2 solution = 8.96 volume.
