This Science quiz will test you on acid reactions. Acids are chemicals which readily release hydrogen ions into solution. This property makes them react in predictable ways with other substances, in particular metals and bases.
At GCSE level you need to know what will be made when hydrochloric or sulfuric acid react with a metal, and when hydrochloric, sulfuric or nitric acid are neutralised by a base. A base is any substance that will neutralise an acid, and an alkali is simply a soluble base.
