At various points on the temperature scale, you can find solids that are almost infinitely soluble with water, because it’s *just* below their melting point and they’re miscible when liquid. (Electronegativy is the tendancy to attract the bonding electrons in a covalent bond.) But the halide ions in (Silver Chloride) AgCl, AgBr, and Agl, are very much polarized, so covalent character predominates in these salts and they are insoluble in water. yes it is soluble "soluble" is not a scientific term. First off, MgF2 is an ionic compound. Where have I gone wrong? A common ion, either Ca2+ or F- will decrease the solubility even more as explained by Le Chatelier's principle.
