Key Stage 4
Meaning
Potassium Hydroxide is a solid (STP) chemical compound with the formula KOH.
About Potassium Hydroxide
- Potassium Hydroxide is a base.
- Aqueous Potassium Hydroxide is an alkali.
- Potassium Hydroxide is held together by ionic bonds.
- Potassium Hydroxide has a giant ionic structure.
- Potassium Hydroxide reacts with acids to produce a Potassium salt:
- Hydrochloric Acid + Potassium Hydroxide → Potassium Chloride + Water
- HCl + KOH → KCl + H2O
- Sulphuric Acid + Potassium Hydroxide → Potassium Sulphate + Water
- H2SO4 + 2KOH → K2SO4 + 2H2O
- Nitric Acid + Potassium Hydroxide → Potassium Nitrate + Water
- HNO3 + KOH → KNO3 + H2O
