The amount of charge required to liberate $11.5 \ g$ of sodium is .....

The $SI$ unit of electrochemical equivalent is

Electrolysis of dilute aqueous $NaCl$ solution was carried out by passing $10 \ mA$ current. The time required to liberate $0.01 \ mol$ of $H_2$ gas at the cathode is $(1 \ F = 96500 \ C \ mol^{-1})$

$Al_2O_3$ is reduced by electrolysis at low potential and high current. If a current of $4 \times 10^4 \ A$ is passed through molten $Al_2O_3$ for $6 \ h$,how many grams of $Al$ will be produced? (Assume $100\%$ current efficiency and atomic mass of $Al = 27 \ g \ mol^{-1}$)

Calculate the amount of electricity required to convert $1.1 \ mol$ of $Cr_2O_7^{2-}$ to $Cr^{3+}$ in acidic medium.

For depositing $1 \ g$ of $Cu$ in a copper voltameter by passing $2 \ A$ of current,the time required will be (For copper $Z = 0.00033 \ g/C$)
