Key Stage 3
Meaning
Sodium Hydroxide is a solid (at room temperature) chemical compound with the formula NaOH.
About Sodium Hydroxide
- Sodium Hydroxide is a base.
- When Sodium Hydroxide is dissolved in water it is an alkali.
- Sodium Hydroxide reacts with acids to produce a Sodium salt:
Key Stage 4
Meaning
Sodium Hydroxide is a solid (STP) chemical compound with the formula NaOH.
About Sodium Hydroxide
- Sodium Hydroxide is a base.
- Aqueous Sodium Hydroxide is an alkali.
- Sodium Hydroxide is held together by ionic bonds.
- Sodium Hydroxide has a giant ionic structure.
- Sodium Hydroxide reacts with acids to produce a Sodium salt:
- Hydrochloric Acid + Sodium Hydroxide → Sodium Chloride + Water
- HCl + NaOH → NaCl + H2O
- Sulphuric Acid + Sodium Hydroxide → Sodium Sulphate + Water
- H2SO4 + 2NaOH → Na2SO4 + 2H2O
- Nitric Acid + Sodium Hydroxide → Sodium Nitrate + Water
- HNO3 + NaOH → NaNO3 + H2O
