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
\(HCl(aq) + Li(s) → LiCl(aq) + H_2(g)\)
\(6HCl(aq) + 2Fe(s) → 2FeCl_3(aq) + 3H_2(g)\)
\(H_2SO_4(aq) + 2K(s) → K_2SO_4(aq) + H_2(g)\)
\(3H_2SO_4(aq) + 2Al(s) → Al_2(SO_4)_3(aq) + 3H_2(g)\)
\(2HNO_3(aq) + Mg(s) → Mg(NO_3)_2(aq) + H_2(g)\)
\(6HNO_3(aq) + 2Ti(s) → 2Ti(NO_3)_3(aq) + 3H_2(g)\)
\(2CH_3COOH(aq) + 2Na(s) → 2CH_3COONa(aq) + H_2(g)\)
\(2CH_3COOH(aq) + Ca(s) → (CH3COO)_2Ca(aq) + H_2(g)\)
