Strength or concentration of H_(2)O_(2) solution is expressed in the following ways: In terms of volume of O_(2) gas: The volume (in mL) of O_(2) gas produced at STP on heating one volume (or 1 mL) of H_(2)O_(2) solution is known as the concentration ofH_(2)O_(2) solution. The commercial samples are marked as "10 volume, 20 volume 30 volume.etc.. A5.0 mL solution of Hydrogen peroxide liberates 1.27g of iodine from an acidified Kl solution. The percentage strength of H_(2)O_(2) is

The percentage strength of H_(2)O_(2) is
Answer» `11.2` `5.6` `1.7` `3.4` Solution :`H_(2)O_(2)+2KI to 2KOH+I_(2)` `W_(H_(2)O_(2))=(1.27)/(254)xx34 rArr ((W)/(V))%=3.4%`
