Allotropes are substances with the same chemical formula but have different forms (e.g. crystal structure). An example of an allotropic pair is aragonite and calcite. The chemical formula of aragonite and calcite is CaCO3. Due to the difference in their crystal structure, their Ksp values are different. The Ksp of aragonite is 6.0×10^(-9) while that of calcite is 3.36×10^(-9). Write the chemical equation for the dissociation of CaCO3 in water. Write the Ksp expression for CaCO3. Which between aragonite and calcite is more soluble? Why?
