The relation between Faraday constant $F$,electron charge $e$,and Avogadro number $N$ is:

In an experiment,$0.04 \ F$ was passed through $400 \ mL$ of a $1 \ M$ solution of $NaCl$. What would be the $pH$ of the solution after the electrolysis? (Change in volume will be negligible)

For the given reaction how much quantity of electricity in Coulomb is required? $\frac{2}{3} Al_2O_3 \rightarrow \frac{4}{3} Al + O_2$

Copper is a divalent metal. The value of its electrochemical equivalent is $3.29 \times 10^{-4} \ g/C$. Its atomic mass is (in $g/mol$)

When an electric current is passed through acidified water at $STP$,$112 \ mL$ of hydrogen gas is collected at the cathode in $965 \ s$. What is the current in amperes?

$A$ current of $0.4 \ A$ is passed through excess of molten $MgCl_2$ for $9.65 \times 10^4 \ sec$. The mass of $Mg$ deposited at the cathode is .............. $gm$
