  - Acts as an antacid and is used in fire extinguishers.
- Acetone:
  - Colorless liquid, used as a solvent and nail polish remover.
  - Highly flammable and volatile.
- Urea:
  - Nitrogenous waste product, used as a fertilizer.
  - Significant in the urea cycle in mammals.
- Sodium Carbonate:
  - Known as washing soda, used in cleaning and glass production.
- Calcium Sulphate:
  - Used in agriculture and construction (as plaster of Paris).
