  6. Reactions with acid and metals/metal compounds
    meatal salts
    most reactions form metal salts to write the name of a metal salt we take the metal used then add the modified name of the acid used, eg when HCl is used we get a metal chloride, when Nitric acid is used we get a metal nitrate, when sulphuric acid is used we get metal sulphate, and when ethanoic acid is used we get metal ethanoate
