Q: One crystalline form of calcium carbonate is the mineral sold as what?


Read this paragraph and choose the correct option from the provided answers:

In our calculation, we have ignored the reaction of the weakly basic anion with water, which tends to make the actual solubility of many salts greater than the calculated value. Exercise One crystalline form of calcium carbonate (CaCO3) is the mineral sold as “calcite” in mineral and gem shops. The solubility of calcite in water is 0.67 mg/100 mL. Calculate its Ksp. Answer: 4.5 × 10−9.

 Choices:

- quartz

- basalt

- salt

- calcite


A:
calcite
