The reaction can be simplified to
The other ions remain constant because they are not affected by the reaction. They are called spectator ions.
Acids and oxidesEdit
- H2SO4 + CuO —> CuSO4 + H2O
- 2 HNO3 + Na2O —> 2 NaNO3 + H2O
The general equation is:
- acid + oxide = salt + water
Acids and hydroxidesEdit
- HCl + NaOH —> NaCl + H2O
Acids and carbonatesEdit
- 2 CH3COOH + CaCO3 —> Ca(CH3COO)2 + CO2 + H2O
The products of an acid-carbonate reaction is a soluble salt, carbon dioxide and water.
