1.	`Cu^(2+)+2e^(-) rarr Cu.` On increasing `[Cu^(2+)]`, electrode potentialA. IncreasesB. DecreasesC. No changeD. First increases, then decreases
Answer» Correct Answer - a `Cu^(2+)(aq)+2e^(-)rarrCu(s)` ltbr. `E_(Cu^(2+)\|Cu)=E^(c-)._(Cu^(2+)\|Cu)-(0.059)/(2)log .(1)/([Cu^(2+)])` `=E^(c-)._(Cu^(2+)\|Cu)+(0.059)/(2)log.[Cu^(2+)]` If `[Cu^(2+)]` increases, `E_(Cu^(2+)\|Cu)` also increases.
