Key Stage 3
Meaning
Acid + Metal Oxide → Metal Salt + Water is the general equation for a neutralisation reaction between a Metal Oxide and an acid.
About 'Acid + Metal Oxide' Reactions
- Acid + Metal Oxide reactions are exothermic so the there will be a temperature rise.
- The reaction between a Metal Oxide and an acid produces water
- The reaction between a Metal Oxide and an acid produces a Metal Salt.
Examples
Acid + Metal Oxide → Metal Salt + Water
- Hydrochloric Acid + Lithium Oxide → Lithium Chloride + Water
- Hydrochloric Acid + Iron Oxide → Iron Chloride + Water
- Sulphuric Acid + Potassium Oxide → Potassium Sulphate + Water
- Sulphuric Acid + Aluminium Oxide → Aluminium Sulphate + Water
- Nitric Acid + Magnesium Oxide → Magnesium Nitrate + Water
- Nitric Acid + Titanium Oxide → Titanium Nitrate + Water
- Citric Acid + Sodium Oxide → Sodium Citrate + Water
- Citric Acid + Nickel Oxide → Nickel Citrate + Water
- Ethanoic Acid + Calcium Oxide → Calcium Ethanoate + Water
- Ethanoic Acid + Manganese Oxide → Manganese Ethanoate + Water
Key Stage 4
Meaning
Acid + Metal Oxide → Metal Salt + Water is the general equation for a neutralisation reaction between a Metal Oxide and an acid.
About 'Acid + Metal Oxide' Reactions
- Acid + Metal Oxide reactions are exothermic so the there will be a temperature rise.
- Acid + Metal Oxide reactions occur when the Metal in the Metal Oxide is more reactive than Hydrogen. This means the metal can lose electrons more easily than Hydrogen can.
- During an Acid + Metal Oxide reaction the H+ ions gain an electron from the Metal and bond with the Oxygen to produce water.
