- Electrolysis of Salt Solution
- Important Source of Chemicals
- 2) Electrolyse the salt solution, this means passing an electric current through it.
- Electrolysis causes chemical change, it splits the solution into Hydrogen, Chlorine and Sodium Hydroxide
- Useful products
- Sodium Hydroxide: 1) Its a very strong alkali and used widely in the chemical industry, 1) Soap, 2) Ceramics, 3) Organic Chemicals, 4) Paper pulp, 5) Oven cleaner, 6) Household bleach
- Household bleach is made by reacting chlorine with sodium hydroxide
- Large scale Electrolysis
- 1) Large scale electrolysis needs a lot of energy. This often comes from burning fossil fuels, which releases Carbon Dioxide (pollutant) into the atmosphere and uses up resources
- 2) Mercury is a toxic chemical used in many brine electrolysis plants
- Important Source of Chemicals
- 1) Salt is also important for the chemical industry.

- Important Source of Chemicals
- Chlorine used in: 1) Disinfectants 2) Killing Bacteria 3) Household Bleach 4) Plastics (PVC) 5) Hydrochloric Acid (HCl) 6) Insecticides

- Useful products
- Hydrogen: 1) Used to make ammonia, 2) Used to change oils into fats for making margarine, 3) Used as a fuel in fuel cells and for welding and metal cutting.
- 3) Asbestos is often used in industrial electrolysis. Asbestos is a toxic chemical and can cause lung cancer
