what can we say about the solubility of chlorides of Mg, Ca, and Ba?
The solubility of chlorides of Mg, Ca, and Ba generally increases as you move down the group in the periodic table. Specifically:
- Magnesium chloride (MgCl2) is soluble in water, forming a clear solution.
- Calcium chloride (CaCl2) is also soluble in water, forming a clear solution.
- Barium chloride (BaCl2) is highly soluble in water, forming a clear solution with no precipitation.
Overall, the trend in solubility of these chlorides follows the trend of increasing solubility as you move down the alkaline earth metal group in the periodic table.
