Text Solution

Verified by Experts

The correct Answer is:
A
% of hydrogen can be calculated as,
Molecular mass of `H_2O, = 2xx1+16xx2 = 34`
` therefore ` percentage of hydrogen = `2/34 xx 100 =5.88%`

What is meant by 10 volume of Hydrogen peroxide (H_2O_2) ?

The percentage by volume of C_(3)H_(8) in a gaseous mixture of C_(3)H_(8),CH_(4) and CO is 20. When 100mL of the mixture is burnt in excess of O_(2) the volume of CO_(2) produced is :

The strength of H_(2)O_(2) is expressed in several ways like molarity, normality,% (w/V), volume strength, etc. The strength of "10 V" means 1 volume of H_(2)O_(2) on decomposition gives 10 volumes of oxygen at 1 atm and 273 K or 1 litre of H_(2)O_(2) gives 10 litre of O_(2) at 1 atm and 273 K The decomposition of H_(2)O_(2) is shown as under : H_(2)O_(2)(aq) to H_(2)O(l)+(1)/(2)O_(2)(g) H_(2)O_(2) can acts as oxidising as well as reducing agent.
