Alkalinity 6
Alkalinity 6 : Chemistry and Chemical Disasters. The combining power of a base measured by the maximum number of equivalents of an acid with which it can react to form a salt. In water analysis, it represents the carbonates, bi-carbonates, hydroxides, and occasionally the borates, silicates, and phosphates in the water. It is determined by titration with standard acid to certain datum points. See API RP 13B for specific directions for determination of phenolphthalein (P) and methyl orange (M) alkalinities of the filtrate in drilling fluids and the alkalinity of the mud itself (P). Also, See (P), (M), and (P). (Bul D11)
