Alkalinity measures the acid-neutralizing capacity of a water sample. The alkalinity in a water sample measured by the amount of standard acid needed to lower the pH. Based on stoichiometry of the reaction and number of moles of Sulphuric acid needed to reach the end point, the concentration of alkalinity in water is calculated. Total Alkalinity

A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H + ions and OH – ions which form water. A neutralisation reaction is generally an acid-base neutralization reaction.
