Neutralization

n. act of making neutral; process of neutralizing; making ineffective (also neutralisation)

Neutralization is a chemical reaction, also called a water forming reaction, in which an acid and a base or alkali (soluble base) react and produce a salt and water(H2O). In other words, it can be said that neutralization is the combination of hydrogen ions H+ and hydroxide ions OH− (or oxide ions O2−) to form water molecule H2O. In the process, a salt is formed. In the process of neutralization a proton (usually hydrogen) is transferred. An acid is a proton donor, while a base is a proton receiver. H2O can act as either an acid or a base, depending on whether it comes in contact with an acid or a base (it takes the opposite form) Neutralization is generally exothermic, meaning it produces heat. One example of an endothermic neutralization is that of baking soda and vinegar (or other weak acids)
