SaltAn ionic Compound formed by the reaction of an acid and a base. The products of the reaction of an acid and a base are a salt and water. For example, the base AgOH reacts with the acid HNO3 to form the salt AgNO3 and water; A chemical Compound consisting of an assembly of cations [+] and anions [-]; compounds with ionic chemical bonds. In solution, salts may be neutral, weakly acidic or weakly alkaline. The Handbook of Chemistry and Physics, 91st edition (2010-2011) defines a salt as an ionic Compound formed by the reaction of an acid and a base. In chemistry, such reactions are real or they are hypothetical. For example, a real salt producing chemical reaction occurs when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), a base, resulting in the formation of sodium chloride (NaCl) or table salt. As another example, when hydrochloric acid (HCl) reacts with ammonium hydroxide (NH4OH), a base, a salt called ammonium chloride (NH4Cl) forms. However, this is reaction is hypothetical because the chemical species called ammonium hydroxide does not actually exist as a stable entity.
