Q 2614180059.     `H_2O_2` acts as both oxidising as well as reducing agent. its product is `H_2O_2, when act as oxidising anent and its produc is `O_2` when act as of reducing agent. The Btrength of' 10V means one liter of `H_2O_2` solution on decomposition at S. T. P. condintion liberate 10 liters of oxygen gas `(H_2O_2 -> H_2O + 1/2 O_2)` 15 gm `Ba(MnO_4)_2` sample containing inert impurity is completely reacting with 100 rnl of' 11.2 V' `H_2O_2` , then what will be the % purity of `Ba (MnO_4 )_2` in the sample?
