Strength of the sample of H_(2)O_(2) is generally expressed in terms of volume strength . It means the volume of oxygen liberated at NTP by heating one volume of H_(2)O_(2) . The concentration of H_(2)O_(2) ina solution can also expressed as percentage of H_(2)O_(2) in solution . Normality of this solution can be calculated if the equivalent mass of H_(2) O_(2) is known . 25 mL of H_(2)O_(2) solution was added to the excess of acidified KI solution . The iodine so liberated required 40 mL of 0.1 N Na_(2)S_(2)O_(3) solution . what is normality of H_(2)O_(2) solution ?
