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 electricity is passed through a solution of $AlCl_3$,$13.5 \ g$ of $Al$ is deposited. What is the number of Faradays used?

What is achieved by Faraday using the principles of electrolysis?

The quantity of silver deposited when one coulomb charge is passed through $AgNO_3$ solution:

The electrochemical equivalent of a metal is $x \ g \ C^{-1}$. The equivalent weight of the metal is:

$A$ silver voltameter is connected in series with a water voltameter and an electric current is passed through them. At the end of electrolysis,the weight of the cathode in the silver voltameter increases by $0.108 \ g$. What is the volume of oxygen liberated at $STP$ in $mL$?
