Which statements is/are correct ?

Answer»

In voltaic cell OXIDATION occurs at at anode
In an electrolitic cell reduction occurs at cathode
In a CONDUCTIVITY cell electrolysis does not take place
`H^(+)` has greater CONDUCTANCE then `OH^(-)`

Solution :In voltic cell oxidation occur at anode
anode ` Zn//Z^(+2)////Cu^(+2)//Cu`
`(-ve)"anodecathode" 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 )
