On passing the current in a water voltameter,the hydrogen is:

$NaOH$ is manufactured by the electrolysis of a brine solution. The products of the reaction are:

The resulting solution obtained at the end of electrolysis of concentrated aqueous solution of $NaCl$ . . . . . . .

Which of the following is $NOT$ true about the electrolysis of molten $NaCl$?

The number of electrons delivered at the cathode during electrolysis by a current of $1 \ A$ in $60 \ s$ is (charge on electron $= 1.60 \times 10^{-19} \ C$)

If $0.50 \ L$ of a $0.60 \ M$ $SnSO_4$ solution is electrolyzed for a period of $30.0 \ min$ using a current of $4.60 \ A$ with inert electrodes,what is the final concentration of $Sn^{2+}$ remaining in the solution? (Atomic weight of $Sn = 119$)
