The following two reaction can occur during electrolysis of aqueous sodium chloride solution
`Na^(+)(aq)+E^(-)rarrNa(s)E^(@)=-2.71 V`
`2H_(2)O(l)+2E^(-)rarrH_(2)(g)+2 OH^(@)(aq)E^(@)=-0.83 V`
Which reaction takes place preferentially and why ?

Text Solution

Verified by Experts

Since `E^(@)` of `H_(2)O` is higher than that of `Na^(+)` ions therefore reduction of `H_(2)O` to takes place preferentially to evolve `H_(2)` gas at the cathode
