$1 \ C$ of electricity deposits:

Which of the following compounds is formed when electrolysis of brine solution takes place?

What will be the products obtained at cathode and anode respectively,on electrolysis of aqueous solution of $AgNO_3$ with platinum cathode and silver anode?

The electroplating of $Cr$ is undertaken because:

When electric current is passed through a cell having an electrolyte,the positive ions move towards the cathode and the negative ions towards the anode. If the cathode is pulled out of the solution,what happens to the ions?

Write the reactions for the following electrolytic processes:
$A$. Electrolytic reaction of concentrated aqueous solution of $NaCl$ (Brine).
$B$. Electrolytic reaction of dilute aqueous solution of $NaCl$.
