Question

how many Faraday's are needed to reduce 3g mole of Cu2+ to Cu metal ?​

Answer 1

Answer:

Faraday's first law says that the amount of electricity passed through the electrode is directly proportional to the number of substances liberated from it.

To reduce 3g mole of cu2+to Cu metal =cu²+2e‐ gives Cu

Explanation:

it is so cause there are two moles of reactant present in this reaction thus the amount of charge required is 2F.
