A ==Key Stage 3=====Meaning===[[Neutralisation]] is a [[Chemical Reaction|chemical reaction]] in which an [[acid]] and a [[base]] or [[alkali]] [[Chemical Reaction|react]] to produce a [[Neutral (Chemistry)|neutral]] [[product]]. ===About Neutralisation===: [[Neutralisation]] can reduce the danger from a [[corrosive]] spill.: An [[acid]] can be '''neutralised''' by adding a [[base]].: A [[base]] can be '''neutralised''' by adding an [[acid]].: When there is a dangerous [[acid]] spill it is better to use an [[insoluble]] base to '''neutralise''' it than an [[alkali]] because if too much is used the [[insoluble]] [[base]] will not make the [[solution]] go above [[pH]] [[Neutral (Chemistry)|7]] but an [[alkali]] may '''neutralise''' and then replace the [[acid]] with another [[corrosive]] [[chemical]] with a high [[pH]]. ===Examples===: [[Hydrochloric Acid]] + [[Lithium Oxide]] → [[Lithium Chloride]] + [[Water]]: [[Hydrochloric Acid]] + [[Iron Oxide]] → [[Iron Chloride]] + [[Water]] : [[Sulphuric Acid]] + [[Potassium Hydroxide]] → [[Potassium Sulphate]] + [[Water]]: [[Sulphuric Acid]] + [[Aluminium Hydroxide]] → [[Aluminium Sulphate]] + [[Water]] : [[Nitric Acid]] + [[Magnesium Carbonate]] → [[Magnesium Nitrate]] + [[Carbon Dioxide]] + [[Water]]: [[Nitric Acid]] + [[Titanium Carbonate]] → [[Titanium Nitrate]] + [[Carbon Dioxide]] + [[Water]]
