Total Alkalinity is determined by the titration to a pH between 3.7 and 5.1, which includes all carbonates, bicarbonates, and hydroxides species. The selected indicator dye changes color within the desired pH range for alkalinity determination. For most analyses, bromcresol green-methyl red is used to indicate a pH endpoint of 4.3 to 5.1. ................
