Calcium ion present in water supplies is easily precipitated as calcite (CaCO3):               Ca2+(aq) + CO32-(aq) ⇌ CaCO3(s)Because the Ksp decreases with temperature, heating hard water forms a calcite “scale,” which clogs pipes and water heaters. Find the solubility of calcite in water (a) at 10°C (Ksp = 4.4 x 10-9) and (b) at 30°C (Ksp = 3.1 x 10-9).
