Identify the solubility rules relevant to the compounds listed. Solubility rules help predict whether a compound will dissolve in water.
According to solubility rules, most salts containing alkali metal ions (like sodium) and the ammonium ion are soluble. Therefore, sodium chloride (NaCl) is soluble in water.
Calcium carbonate (CaCO3) is generally insoluble in water, except in the presence of acids.
Silver chloride (AgCl) is known to be insoluble in water, with only a very small amount dissolving.
Barium sulfate (BaSO4) is also insoluble in water, which is why it is often used in medical imaging as a contrast agent.
