According to Faraday's laws of electrolysis,the amount of decomposition is proportional to

Faraday's $2^{nd}$ law of electrolysis states that the mass of a substance deposited at an electrode is directly proportional to its:

When a current of $0.5 \ A$ is passed for $2 \ hours$ through a molten metal salt,$3.88 \ g$ of the metal was deposited. If the atomic mass of the metal is $208 \ units$,the oxidation state of the metal in the salt is:

When $1 \ C$ of charge is passed through an electrolyte solution,the mass deposited is equal to:

When $4.5 \, A$ current is passed through $1 \, L$ of $0.6 \, M$ $CuCl_2$ solution for $1.15 \, hour$,calculate the mass of $Cu$ and the change in concentration of the solution. $[Cu = 63.5 \, u]$

When an electric current is passed through acidified water,$112 \ mL$ of hydrogen gas at $N.T.P.$ was collected at the cathode in $965 \ seconds$. The current passed,in ampere,is
