Why does `H^(+)` ion always get associated with atoms or molecules ?A. Ionisation enthalpy of hydrogen resembles that of alkali metalB. Its reactivity is similar to halogensC. It resembles both alkli metals and halogensD. Loss of an electron from hydrogen atom results in a nucleus of very small size as compared to other atoms or ions, due to small size it connot exist free.

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 .
