Answer Details

The separation of a mixture of calcium trioxocarbonate (lV) and sodium trioxocarbonate (IV) is most easily carried out by using the differences in their solubility. When two or more substances are mixed together, they may have different solubility in a particular solvent. In this case, calcium trioxocarbonate (IV) and sodium trioxocarbonate (IV) are both soluble in water, but their solubility is different. Calcium trioxocarbonate (IV) is less soluble in water compared to sodium trioxocarbonate (IV). Therefore, by dissolving the mixture in water, the less soluble calcium trioxocarbonate (IV) can be separated from the more soluble sodium trioxocarbonate (IV) by filtration or centrifugation. This method is called fractional crystallization.
