Acids reacting with Metals
Acid + Metal - Salt + Hydrogen
- The more reactive the metal, the faster the reaction takes place.
- Copper does not react with dilute acids at all - its less reactive than hydrogen.
- The name of the salt produces depends on which metal is used, and also which acids are used. If the acid is:
Hydrochloric acid - the salt ends in Chloride e.g. 2HCl + Mg - MgCl2 + H2 (Magnesium Chloride)
Sulphuric acid - The salt ends in Sulphate
e.g. H2SO4 + Mg - MgSO4 +H2 ( Magnesium Sulphate)
Nitrate acid - The salt ends in Nitrate
