In neutralisation of an acid, H+ (aq) ions react with a base to form a salt and neutral water.
The H+ ions from the acid are replaced by metal or ammonium ions from the base.
Hydrochloric acid: HCL Sodium chloride - NaCl
Sulfuric acid: H2SO4 Sodium sulfate - Na2SO4
Nitric acid: HNO3 Calcium nitrate - Ca(NO3)2
Ethanoic acid: CH3COOH Ammonium ethanoate - CH3COONH4
To form a salt, the hydrogen in the acid is replaced by a metal or ammonium ion.
Acid+ Alkali --> salt + water
Acid + carbonate --> salt + water
Acid + metal oxide/metal hydroxide --> Salt + water
