Which of the following is a correct statement ? .

Options

A. Mobility of `H^(o+)` ions in ice is greater as compared to liquid water
B. Mobility of `H^(o+)` ions in ice is less as compared ti liquid water
C. Mobility of `H^(o+)` ions in ice is equal to that in liquid water .
D. Cannot be predicted

Answer

A

Explanation

In liquid water `H^(o+)` ions (obtained from ionisation of `H_(2)O)` are easily hydrated As a result the size of the hybrated `H^(o+)` ions is much larger than in ice Hence their mobility in water is less than in ice .
