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)` in a 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 .
