With respect to a given solvent what do we mean by solubility?
Simply that the solid or the liquid is
And assessment of solubility is an experimental phenomenon, and we can advance reasons to attempt to explain the observed solubility. Water is an exceptionally powerful solvent inasmuch as it can solvate many cations and anions..........
And we write
In hexanes, water has minimal solubility, because the apolar hexanes molecule cannot solvate the dipolar water molecule. On the other hand ethanol, which in infinitely miscible in water, is also SOLUBLE in hexanes. On the other, other hand, methanol, which is infinitely miscible in both water and ethanol, is INSOLUBLE in hexanes. Can you account for these phenomena?
In aqueous solution, general rules of ionic solubility are:
The given rules follow a hierarchy. Alkali metal and ammonium salts tend to be soluble in all circumstances. The one exception to this rule is
