Uses of Bases:
- Ammonia is used in producing fertilisers that manufacture nitric acid to prevent clotting in natural and synthetic latex.
- Aluminium hydroxide Often used to make gastric medicine-antacid.
- Calcium hydroxide Used to make cement and lime water, help with the application of sewage treatment and neutralise soil's acidity.
- Bases are used to make soaps, toothpastes, paper, and rayon.
- They are widely used in the baking industry.
- Bases are used in bleaching powder and for various cleaning purposes.
- They help in cleaning sulphur dioxide from emissions.
- Used in whitewashing to brighten surfaces.
- Important for making detergents.
- Ammonium hydroxide (NH₄OH) is used to remove grease stains from clothes.
- Chalk and oven cleaners are made using bases.
- Acid rain can be neutralised by minerals like limestone (calcium carbonate).
- Scrubbers in power plants use bases like calcium hydroxide to reduce the release of sulphur oxides, which are acidic pollutants.
- Antacids contain bases, such as calcium carbonate, to neutralise stomach acid and relieve heartburn and indigestion.
