- Calcium Hydroxide reacts with acids to produce a Calcium salt:
Key Stage 4
Meaning
Calcium Hydroxide is a solid (STP) chemical compound with the formula Ca(OH)2.
About Calcium Hydroxide
- Calcium Hydroxide is a base.
- Aqueous Calcium Hydroxide is an alkali.
- Calcium Hydroxide is held together by ionic bonds.
- Calcium Hydroxide has a giant ionic structure.
- Calcium Hydroxide reacts with acids to produce a Calcium salt:
- Hydrochloric Acid + Calcium Hydroxide → Calcium Chloride + Water
- 2HCl + Ca(OH)2 → CaCl2 + H2O
- Sulphuric Acid + Calcium Hydroxide → Calcium Sulphate + Water
- H2SO4 + Ca(OH)2 → CaSO4 + 2H2O
- Nitric Acid + Calcium Hydroxide → Calcium Nitrate + Water
- 2HNO3 + Ca(OH)2 → Ca(NO3)2 + H2O
