Key Stage 3
Meaning
Acid + Metal → Metal Salt + Hydrogen is the general equation for a neutralisation reaction between a metal and an acid.
About 'Acid + Metal' Reactions
- Acid + Metal reactions are exothermic so the there will be a temperature rise.
- The reaction between a metal and an acid produces Hydrogen gas which can be seen bubbling from the metal.
- The reaction between a metal and an acid produces a Metal Salt.
Examples
Acid + Metal → Metal Salt + Hydrogen
- Hydrochloric Acid + Lithium → Lithium Chloride + Hydrogen
- Hydrochloric Acid + Iron → Iron Chloride + Hydrogen
- Sulphuric Acid + Potassium → Potassium Sulphate + Hydrogen
- Sulphuric Acid + Aluminium → Aluminium Sulphate + Hydrogen
- Nitric Acid + Magnesium → Magnesium Nitrate + Hydrogen
- Nitric Acid + Titanium → Titanium Nitrate + Hydrogen
- Ethanoic Acid + Calcium → Calcium Ethanoate + Hydrogen
- Ethanoic Acid + Manganese → Manganese Ethanoate + Hydrogen
Key Stage 4
Meaning
Acid + Metal → Metal Salt + Hydrogen is the general equation for a neutralisation reaction between a metal and an acid.
About 'Acid + Metal' Reactions
- Acid + Metal reactions are exothermic so the there will be a temperature rise.
- Acid + Metal reactions occur when the metal is more reactive than Hydrogen. This means the metal can lose electrons more easily than Hydrogen can.
- During an Acid + Metal reaction the H+ ions gain an electron from the metal to produce Hydrogen gas.
Examples
Acid + Metal → Metal Salt + Hydrogen
- Hydrochloric Acid + Lithium → Lithium Chloride + Hydrogen
- Hydrochloric Acid + Iron → Iron Chloride + Hydrogen
- <chem>HCl + Li = LiCl + H2O<chem>
- Sulphuric Acid + Potassium → Potassium Sulphate + Hydrogen
- Sulphuric Acid + Aluminium → Aluminium Sulphate + Hydrogen
