When an aqueous concentrate solution of lithium chloride is electrolysed using inert electrodes:

Options

A. `Cl_2` is liberated at the anode
B. Li is deposited at the cathode
C. as the current flows, pH of the solution around the cathode remains constant
D. as the current flows, pH of the solution around the cathode increases

Answer

A, D

Explanation

Electroes , inert electrodes , Electrolyte , LiCl
`"Anode " : 2Cl^(-) to Cl_2 + 2e^(-) , "Cathode" : 2H^(+) + 2e^(-) to H_2`
`P^(H) = log""(1)/([H^(+)]) ,P^(H)` of solution around cathode increases
