procedure that can be applied to any 1:1 salt of a monoprotic weak acid and under many circumstances for the salts of weak polyprotic acids. Example problem: Calculate the solubility of CaCO 3 at pH 6.5. The K sp of calcium carbonate is 5.0x10-9: CaCO 3(s) → ← Ca 2+ + CO 3 2-K sp = [Ca 2+] [CO 3 2-] (1)

Calcium carbonate occurs naturally as calcite, marble, chalk and decomposes if heated above 800°C and gives carbon dioxide with acids (unless the calcium salt is insoluble in water). It is an approved food additive, E170. Blackboard chalk may be calcium carbonate but is more likely to be calcium sulfate. Magnesium carbonate also occurs naturally.
