What is Acid–base reaction?
{{TopicTOC-Chemistry}} An '''acid-base reaction''' is a [[chemical reaction]] between an [[acid]] and a [[Base (chemistry)|base]]. The products of such a reaction are a salt and water. This reaction may also regarded as neutralization reaction. The reaction can be simplified to :[[hydroxide|{{chem|OH|−}}(aq)]] + {{chem|H|+}}(aq) → [[water (molecule)|{{chem|H|2|O}}]] The other ions remain constant because they are not affected by the reaction. They are called [[spectator ion]]s. == Acids and oxides == An example of an acid-oxide reaction is [[sulfuric acid]] and [[copper(II) oxide]] reacting to form [[copper sulfate]] and [[water]]: :H<sub>2</sub>SO<sub>4</sub> + CuO —> CuSO<sub>4</sub> + H<sub>2</sub>O Another example of an acid-oxide reaction is [[nitric acid]] reacting with sodium oxide to form [[sodium nitrate]] and water: :2 HNO<sub>3</sub> + Na<sub>2</sub>O —> 2 NaNO<sub>3</sub> + H<sub>2</sub>O The general equation is: :acid + oxide = salt + water == Acids and hydroxides == This is one of the more common acid-base reactions. This reaction is one of the few processes to make [[sodium chloride]] using [[hydrochloric acid]] and [[sodium hydroxide]]: :HCl + NaOH —> NaCl + H<sub>2</sub>O == Acids and carbonates == An acid can also react with a carbonate, which is a relatively weak [[Base (chemistry)|base]]. An example is [[acetic acid]] reacting with [[calcium carbonate]] to form calcium acetate, [[carbon dioxide]] and water: : 2 CH<sub>3</sub>COOH + CaCO<sub>3</sub> —> Ca(CH<sub>3</sub>COO)<sub>2</sub> + CO<sub>2</sub> + H<sub>2</sub>O The products of an acid-carbonate reaction is a soluble salt, carbon dioxide and water. {{-}} {{chem-stub}} {{DEFAULTSORT:Acid-base reaction}} [[Category:Chemical reactions]] [[Category:Acids]]
