H_(2)O_(2) reduces

The structure of H_(2)O_(2) is

H_(2)O_(2) is reduced rapidlly by Sn^(2+) to give H_(2)O and Sn^(+)H_(2)O_(2) is decomposed slowly at room temperature so yield O_(2) and H_(2)O . 136g of % by mass of H_(2)O in water treated with 100 mL 3 M Sn^(2+) and then a mixture is allowed to stand until no further reaction occurs. The reactions involved are 2H^(o+)+H_(2)O_(2)+Sn^(2+) to Sn^(2+)+2H_(2)O: 2H_(2)O+O_(2) The valume strength of H_(2)O_(2) left after reacting with Sn^(2+) is

H_(2)O_(2) acts both as oxidant and reductant. H_(2)O and O_(2) are products when H_(2)O_(2) acts as oxidant and reductant respectively. The strength of H_(2)O_(2) is expressed in terms of molarity, normality, % strength and volume strength. H_(2)O_(2) decomposes as H_(2)O_(2)rarrH_(2)+1//2O_(2)(g) i.e., one mole O_(2) is released from 2 mole H_(2)O_(2) .x. .volume. strength of H_(2)O_(2) means 1 volume (mL or litre) of H_(2)O_(2) sample released x volume (mL or litre) O_(2) gas at NTP on its decomposition. Hence molarity = x//11.2 moles per litre, i.e., normality of H_(2)O_(2)=x//5.6 Thus volume strength, i.e., x=5.6xx Normality. Weigth of H_(2)O_(2) (in gm) present in 100 mL H_(2)O_(2) solution is called percentage strength of H_(2)O_(2) How much volume of H_(2)O_(2) solution of 22.4 .vol. strength is required to oxidise 6.3 gm oxalic acid

It is customary to indicate the strength of a sample of H_(2)O_(2) under specification of volume. The strength of H_(2)O_(2) solution can also be in %(w/v) or molarity or normality,"10 Vol H_(2)O_(2) solution means I ml of H_(2)O_(2) solution decomposes to give 10 ml of O_(2) gas at STP. 1 lit of H_(2)O_(2) solution decomposes to give 10 lit of O_(2) gas at STR. The mass of H_(2)O_(2) set in 600ml of to volume lydrogen peroxide solution is

It is customary to indicate the strength of a sample of H_(2)O_(2) under specification of volume. The strength of H_(2)O_(2) solution can also be in %(w/v) or molarity or normality,"10 Vol H_(2)O_(2) solution means I ml of H_(2)O_(2) solution decomposes to give 10 ml of O_(2) gas at STP. 1 lit of H_(2)O_(2) solution decomposes to give 10 lit of O_(2) gas at STR. The volume of ''20 V H_(2)O_(2) solution required to prepares is 5 litres of oxygen at STP is

How will be the strength of H_(2)O_(2) determined ?

Specific test for the detection of H_(2)O_(2) is

Three vessels (A, B, C) contain H_(2)O_(2) solution. In vessel A , 500 mL of 10 vol H_(2)O_(2) is present. 100 mL of 3 vol H_(2)O_(2) is present in vessel B. Vessel C is filled with 250 mL of 2M H_(2)O_(2) . The weight (in g) of H_(2)O_(2) persent in these vessels follows the order
