What is the percentage strength of a solution of 100 volume `H_(2)O_(2)`?

Text Solution

Verified by Experts

100 volume solution means that 1 L this `H_2O_2` solution will give 100 L of oxygen at STP.

From equation,
22.4 L of `O_2` at STP is obtained from `H_2O_2` = 68 g
`100L " of " O_2` at STP is obtained from `H_2O_2=68/22.4xx 100`
`=303.57g//L`
`=30% H_2O_2` solution

The strength of H_(2)O_(2) is expressed in many ways like molarity , normality , % strength and volume strengths But out of all these form of strengths , volume strength has great significance for chemical reactions . This decomposition of H_(2)O_(2) is shown as under H_(2)O_(2)(l) to H_(2)O(l) + (1)/(2)O_(2)(g) 'x' volume strength of H_(2)O_(2) means one volume (litre or ml) of H_(2)O_(2) releases x volume (litre or ml) of O_(2) at NTP . 1 litre H_(2)O_(2) release x litre of O_(2) at NTP =(x)/(22.4) moles of O_(2) From the equation , 1 mole of O_(2) produces from 2 moles of H_(2)O_(2) . (x)/(22.4) moles of O_(2) produces from 2xx(x)/(22.4) moles of H_(2)O_(2) =(x)/(11.2) moles of H_(2)O_(2) So, molarity of H_(2)O_(2)=((x)/(11.2))/(1)=(x)/(11.2)M Normality =n-factor xx molarity =2xx(x)/(11.2)=(x)/(5.6) N What is the percentage strength of "15 volume" H_(2)O_(2) ?
