Solution of Sulphuric Acid with Platinum Electrode
• Electrolysis is a process where an electric current is passed through a conducting solution to cause a chemical reaction.
• In this case, when a solution of sulphuric acid (H2SO4) is electrolyzed using a platinum electrode, the acid dissociates into ions.
• The H2SO4 solution contains H+ and SO4^2- ions.
• At the anode (positive electrode), the SO4^2- ions are attracted and give up electrons to form oxygen gas and water. The overall reaction at the anode is:
2 SO4^2- → O2 + 2 SO4^2- + 4 e-
• At the cathode (negative electrode), the H+ ions are attracted and gain electrons to form hydrogen gas. The overall reaction at the cathode is:
2 H+ + 2 e- → H2
• This process separates the components of the sulphuric acid solution into oxygen gas and hydrogen gas.

Aqueous Solution of AgNO3 with Ag Electrode
• When an aqueous solution of silver nitrate (AgNO3) is electrolyzed using a silver electrode, the silver nitrate dissociates into silver ions (Ag+) and nitrate ions (NO3-).
• At the anode (positive electrode), the silver ions are attracted and gain electrons to form solid silver metal. The overall reaction at the anode is:
Ag+ + e- → Ag
• At the cathode (negative electrode), the nitrate ions are attracted and give up electrons to form nitrogen gas and oxygen gas. The overall reaction at the cathode is:
2 H2O + 2 e- → H2 + O2
• This process results in the deposition of silver metal on the silver electrode and the release of nitrogen and oxygen gases.
