Key Stage 3
Meaning
Calcium Oxide is a solid (at room temperature) chemical compound with the formula CaO.
About Calcium Oxide
- Calcium Oxide is a base.
- Calcium Oxide reacts with acids to produce a Calcium salt and water.
Key Stage 4
Meaning
Calcium Oxide is a solid (STP) chemical compound with the formula CaO.
About Calcium Oxide
- Calcium Oxide is a base.
- Calcium Oxide is held together by ionic bonds.
- Calcium Oxide has a giant ionic structure.
- Calcium Oxide reacts with acids to produce a Calcium salt and water.
- Hydrochloric Acid + Calcium Oxide → Calcium Chloride + Water
- 2HCl + CaO → 2CaCl2 + H2O
- Sulphuric Acid + Calcium Oxide → Calcium Sulphate + Water
- H2SO4 + CaO → CaSO4 + H2O
- Nitric Acid + Calcium Oxide → Calcium Nitrate + Water
- 2HNO3 + CaO → Ca(NO3)2 + H2O
