1.	30ml of sample of hydrogen peroxide solution after acidification with dil. H_2SO_4required 30ml of 0.02M KMnO_4solution for complete oxidation. Calculate molarity and percentage strength of the solution.
Answer» Solution :`KMnO_(4)+5H_(2)O_(2)+3H_(2)SO_(4)toK_(2)SO_(4)+2MnSO_(4)+8H_(2)O+5O_(2)` 2 moles of `KMnO_(4)` = 5 moles `H_(2)O_(2)` The equation for titration `(M_(1)V_(1))/(n_(1))=(M_(2)V_(2))/(n_(2))=(30xx0.02)/(2)=(M_(H_(2)O_(2))xx30)/(5)` MOLARITY of `H_(2)O_(2)` solution `M_(H_(2)O_(2))=(5)/(2)xx0.02M=0.05M` (w/v)% of `H_(2)O_(2)` solution`=Mxx"G.M.W//10=0.05xx34//10=0.17%
