If a current of $0.5 \ A$ is passed through a solution of $AgNO_3$ for $193 \ s$,$0.108 \ g$ of $Ag$ is deposited. What is the equivalent weight of $Ag$?

When a current of $0.6 \ A$ is passed through an aqueous solution of $CuSO_4$ for $7 \ minutes$,what is the total quantity of electricity passed in Faradays?

During the electrolysis of concentrated $H_2SO_4$,perdisulphuric acid $(H_2S_2O_8)$ and $O_2$ are formed in equimolar amounts. The amount of $H_2$ that will be formed simultaneously is $(2H_2SO_4 \rightarrow H_2S_2O_8 + 2H^+ + 2e^-)$

The quantity of electricity required to liberate $112 \, cm^3$ of hydrogen at $STP$ from acidified water is

$6.5 \, g$ of $Mg$ is deposited during the electrolysis of fused $MgCl_2$. What will be the volume of chlorine gas (in $L$) discharged at the electrode at $STP$?

$A$ $250.0 \ mL$ sample of a $0.20 \ M \ Cr^{3+}$ is electrolyzed with a current of $96.5 \ A$. If the remaining $[Cr^{3+}]$ is $0.1 \ M$,the duration of the process is $............. \ s$ (Atomic weight of $Cr = 52$).
