4 points) A drinking water at pH 7.2 contains 8x104 M TOT Ca and has an alkalinity of 80 mg/lL as CaCo, provided entirely by species of the carbonate group. It is desired to adjust the pH of this water to cause calcite to be slightly supersaturated for the purposes of corrosion control. How much lime must be added to achieve a saturation index of 0.2? What would the pH of the water be? You can use Aquachem wherever it is applicable. Caen_-âG"t
