What is the volume strength of H2O2 of its 11.2 ml requires 30 ml of 0.5 M 2Cr2O7?
What is the volume strength of H2O2 of its 11.2 ml requires 30 ml of 0.5 M 2Cr2O7? Correct Answer 45
Volume strength of H2O2 = 11.2 × M H2O2 = 5.6 × N H2O2 neq (H2O2) = neq (KMnO4) M × 11.2 × 2 = 0.5 × 30 × 6 M = 4.017. Therfore, Volume strength = 11.2 × 4 = 45.
