Which statements is/are correct ?

Options

A. In voltaic cell oxidation occurs at at anode
B. In an electrolitic cell reduction occurs at cathode
C. In a conductivity cell electrolysis does not take place
D. `H^(+)` has greater conductance then `OH^(-)`

Answer

A, B, C, D

Explanation

In voltic cell oxidation occur at anode
anode ` Zn//Z^(+2)////Cu^(+2)//Cu`
`(-ve)" anode cathode" Zn to 2e^(-) + Zn^(+2)`
chemical energy ` to` electrical energy , In electrolytic cell reduction occur at cathode cathode Electrical energy ` to ` Chemical energy at cathode `B^(+) + e^(-) to ` B (reduction )
