Titration is simply the slow addition of one solution of known strength (concentration) to another solution of unknown strength until neutralization. Acid/Base Neutralization •A salt is any compound that can be derived from the neutralization of an acid and a base. The most common example is the formation of NaCl such as 2Na (metal) + Cl 2 (halogen) → 2NaCl (salt) The reaction between an acid and base always results in the formation of salt and water due to neutralization reaction such as HCl + NaOH → NaCL + H 2 O Some other examples of neutralization are 1. This is a standard calculation that is dependent on the acid and base used in the reaction to produce the water and salt. A chemical equation is the representation of the chemical reactions. H = Q + pV. The same equation relating the concentrations of acid and base applies. Neutralisation (or neutralization) was defined by Arrhenius as a reaction in which hydrogen ions (H +) combine with hydroxide ions (OH -) to form water (H 2O) 1: H + + OH - → H 2O. Neutralization: the reaction between an acid and a base that forms salt and water. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored.

Use uppercase for the first character in the element and lowercase for the second character. Neutralizationrefers to a chemical reaction in which an acid and a base interact to form water and salt as products.The method is based on the fact that one gram equivalent of the acid completely neutralizes one gram equivalent of the base and vice versa. Neutralization is a chemical process of making salt and water using acid and base as reactants. The balanced chemical equation representing the neutralization of hydrochloric acid with sodium hydroxide is: HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l) + heat.
