The reasons why solutions will form will be explored in this section, along with a discussion of why water is used most frequently to dissolve substances of various types. Compare the boiling points of 3 molecules with the same molar mass. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont. Such solutions are called supersaturated solutions and are not stable; given an opportunity (such as dropping a crystal of solute in the solution), the excess solute will precipitate from the solution.The figure below illustrates the above process and shows the distinction between unsaturated and saturated. 25 What is the boiling point of a solution, A:Tb = Kb x Molality +10.5 ; Viana, R.B.
