Products obtained on electrolysis of brine are :

The electrolysis of brine (sodium chloride solution) produces several useful products. Here are the steps:

1. Electrolysis: Brine is electrolyzed by passing an electric current through it. This process separates the sodium chloride into its components.

2. At the Cathode (negative electrode): Hydrogen gas is produced. The reaction is: 2H2O(l) + 2e- → H2(g) + 2OH-(aq)

3. At the Anode (positive electrode): Chlorine gas is produced. The reaction is: 2Cl-(aq) → Cl2(g) + 2e-

4. In the Solution: The hydroxide ions (OH-) from the cathode reaction react with the remaining sodium ions (Na+) in the solution to form sodium hydroxide (NaOH). The reaction is: Na+(aq) + OH-(aq) → NaOH(aq)

So, the products obtained from the electrolysis of brine are hydrogen gas, chlorine gas, and sodium hydroxide.
