A current of 5 A is passed through 3.1 litres of a solution of `CuSO_4` for 10 minutes. What is the pH of the solution?

Text Solution

Verified by Experts

`CuSO_(4) rarrCu^(2+)+SO_(4)^(2-)`
at anode :`2H_(2)O rarrO_(2)+4H^(+)+4e^(-)`
1 Faraday =1 equivalent of `H^(+)` ions
`pH=-log [H^(+)]=-log[10^(-2)]2`
