Base (chemistry) increase the hydronium (HO) concentration in water, whereas bases reduce this concentration. A reaction between an acid and base is called neutralization. In a neutralization reaction, an aqueous solution of a base reacts with an aqueous solution of an acid to produce a solution of water and salt in which the salt separates into its component ions. If the aqueous solution is saturated with a given salt solute, any additional such salt precipitates out of the solution. The notion of a base as a concept in chemistry was first introduced by the French chemist Guillaume François Rouelle in 1754. He
Neutralization (chemistry) In general, for an acid AH at concentration "c" reacting with a base B(OH) at concentration "c" the volumes are related by: An example of a base being neutralized by an acid is as follows. The same equation relating the concentrations of acid and base applies. The concept of neutralization is not limited to reactions in solution. For example, the reaction of limestone with acid such as sulfuric acid is also a neutralization reaction. Such reactions are important in soil chemistry. A strong acid is one that is fully dissociated in aqueous solution. For example, hydrochloric acid, HCl, is a
