Answer 2

Answer:

Electrolysis is a method used in chemistry by which complex substances or compounds are broken down into simpler substances when electricity is passed through it. During this process, the positively charged ions are attracted towards the negatively charged electrode and the negatively charged ions are attracted towards the positive electrode.

Dilute hydrochloric acid is a mixture of HCI and water. So, the electrolysis of HCI and water takes place.

For HCI, Chlorine gas is produced at the anode and Hydrogen gas is evolved at the cathode. The presence of Hydrogen gas is indicated by a squeaky pop from a lighted splint and the presence of Chlorine gas is indicated by the change of the litmus paper from blue to red, and then white (bleaching effect).

For water, oxygen ions are formed at the anode and hydrogen is formed at the cathode.
