Answer

The solubility of calcium carbonate is very small compared to that of potassium carbonate (about 168,000 times smaller). Therefore, we could try to dissolve a known amount of each powder in water. The substance that barely dissolves is calcium carbonate, while the one that will most likely completely dissolve is potassium carbonate.
