Gas produced at anode when water is electrolysed

At STP, 2.8L of oxygen is produced at the anode, during electrolysis of aqueous NaOH solution. Find the volume of the other gas produced at the cathode?

4.5 g Al is produced at the cathode during the electrolysis of molten Al_(2)O_(3) . If the same amount of electricity is passed through acidulated water, then at STP the volume of liberated oxygen at the anode would be -

How will the pH of brine (aq. NaCl solution) be affected when it is electrolysed ?

Sodium reacts with dihydrogen to form a crystalline ionic solid. It is non-volatile and a non-conductor of electricity. It also reacts vigorously with water to liberate H_(2) gas. Write the formula of the ionic solid and give reaction between this solid & water. What happens when the ionic solid in its molten state is electrolysed?

State, with equations, what happens when : Fused ICI is electrolysed.

What happens to the concentration of Ag^(+) ions in a solution of AgNO_(3) when it is electrolysed in presence of Ag-electrodes?

An aqueous solution of sodium sulphate is electrolysed using inert electrodes. The products formed at the cathode and anode respectively are-

Whiich gases are liberated at the cathode and anode during electrolysis of water.

Which is produced in anode and cathode reactions in a lead - acid storage cell during discharging?
