Which of the following elements is obtained by the electrolysis of the aqueous solution of its compound?

During an electrolysis experiment,a current of $100 \ mA$ is passed through a solution of $AgNO_3$ for $30 \ minutes$. Calculate the total charge in Coulombs used.

During electrolysis,the species that becomes neutral at the cathode is ...... .

On passing electric current in an electrolyte solution,$H_2$ gas is liberated at the cathode. Then the electrolyte could be:

During electrolysis of $NaCl$ solution,part of the reaction is $Na^{+} + e^- \to Na$. This is termed as

The platinum electrodes were immersed in a solution of cupric sulphate and electric current was passed through the solution. After some time,it was found that the colour of copper sulphate disappeared with the evolution of gas at the electrode. The colourless solution contains:
