: [[Acid]] + [[Base]] → [[Salt]] + [[Water]]
: When a [[neutralisation]] [[Chemical Reaction|reaction]] happens in [[solution]] the [[Hydrogen Ion (Chemistry)|Hydrogen ions]] and [[Hydroxide Ion (Chemistry)|Hydroxide ion]]s [[Chemical Reaction|react]] to form [[water]].
====Neutralising Acids====
: To [[neutralise]] an [[acid]] it is important to use the right amount of [[base]] or [[alkali]] to [[Product|produce]] a [[neutral (Chemistry)|neutral]] [[substance]]. Too much [[base]] or [[alkali]] and the [[solution]] will not be turned [[alkalinity|alkali]] instead of [[neutral (Chemistry)|neutral]].
An [[acid]] can be [[Neutralise (Chemistry)|neutralised]] with:
*[[Metal]] - Which can be added to [[product|produce]] [[Hydrogen]] [[gas]]. Once no more [[Hydrogen]] is [[product|produced]] the [[solution]] has become [[Neutral (Chemistry)|neutral]].
*[[Insoluble]] [[Carbonate]]s - Which can be added in excess as the [[Chemical Reaction|reaction]] will stop when there is no more [[acid]] and leave the [[insoluble]] [[Carbonate]] visible and a [[Neutral (Chemistry)|neutral]] [[solution]].
*An [[alkali]] with a [[pH Indicator]] - Which will change colour showing when the [[solution]] is [[neutral (Chemistry)|neutral]].
