Neutralisation Year 10 Flashcards
Definition for neutralisation
The reaction between an acid & alkali producing a salt and water
Acid + metal->
Salt + hydrogen
Acid + Alkali* ->
Salt + water
*metal hydroxides and metal oxides
Acid + base ->
Salt + water
Acid + metal carbonate ->
salt + water + carbon dioxide
