Question

Calculate the strength of 10 volume solution of Hydrogen Peroxide.​

Answer 1

10 volume solution of H22 means that 1 litre of this is H2O2 solution will give 10 litre of oxygen at STP.2 H2O2 (l) ➡ O2(g) + H2O (l)2*24 gm 22.7L at STP68gm On the basis of above equation 22.7 litre of O2 is produced from 68 gram H2O2 at STP 10 litre of O2 at STP is produced from(68*10)/22.7 =29.9 gm =30 gm H2O2.Therefore strength of H2O2 in 10 volume H2O2 solution = 30 gm/L = 3 % H2O2 solution.
