Polar molecules are soluble in polar solvents such as water; not in nonpolar solvents. Nonpolar solutes are soluble in nonpolar solvents like hexane C 6 H 14 but are insoluble in water. The above rule does not apply to ionic compounds , since some are soluble in water and others are not. Water soluble ionic compounds such as NaCl forms hydrated ions, Na + (aq) and Cl - (aq). AgCl is insoluble in water, which stays as solids AgCl(s), not as ions. Solubility of ionic compounds are summarized in the table below.

3 The following ion combinations must be memorized. Soluble if Li + , Na + , K + , NO 3 - , or NH 4 + is present Most Cl - containing compounds are soluble, except AgCl and PbCl 2 . Most CO 3 2- , PO 4 3- , S 2- , OH - containing compounds are insoluble, unless Li + , Na + , K + , or NH 4 + is simultaneously present. 9.4 Solution concentrations (= the amount of solute/ the amount of solution) The concentration of a solution is the ratio of the amount of solute (g, mL or mole) to the amount of solution (g, mL or L).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
