Substances vary greatly in their solubilities in various solvents.
There are a few general rules about solubility, which, however, apply in the main to organic compounds. One of these rules is that a substance tends to dissolve in solvents which are chemically similar to it . Inorganic salts are usually more soluble in water or polar solvents and less soluble in non-polar organic solvents. The solubility of a substance may either increase or decrease with increasing temperature. This rule is a consequence of the principle of Le Chatelier.
