Question

how can the concentration of Cu2+ ions in an an aqueous solution be determined with the help of a concentration cell​

Answer 1

let the reaction be

Cu---->2e + Cu2+

Ecell=E°-0.059/2*log[Cu2+]

therefore

E°-Ecell=0.059/2*log[Cu2+]

now simplifying the value and taking antilog will give u your answer
