EXPERIMENT-1 TO DETERMINE THE ALKALINITY IN A …
www.nitsri.ac.inAlkalinity is a measure of the acid-neutralizing capacity of water and is usually determined by titration against sulfuric acid to the endpoint of the acid–base reaction. Alkalinity has two types :-Phenolphthalein alkalinity denoted by (P) and the Total Alkalinity denoted by (T)

www.iitk.ac.inPrinciple and Theory - Alkalinity of water is the capacity of that water to accept protons. It may g be defined as the quantitative capacity of an aqueous medium to react with hydrogen Ions to pH 8'3 'i (phenolphthalein alkalinity) and then to pH 3'7 (total alkalinity or methyl orange alkalinity). The
