Document Summary

Remember the like dissolves like rule when predicting the formation of solutions: polar solvents will dissolve polar solutes and not dissolve nonpolar solutes, non-polar solvents will dissolve non-polar solutes and not dissolve polar solutes. Hsolute values with 3 possible outcomes: 1: the heat of hydration is greater than the hsolute. In some cases, if left undisturbed a supersaturated solution can. In order to maximize the purification, the cooling process must be carried out very slowly. If done correctly, will yield very pure solids that tend to reject impurities. In these cases, equilibrium favors products: some reactions reach equilibrium after most of the product has been consumed. Heterogeneous equilibria: involves reactions that utilize solids and liquids: many chemical reactions will involve pure solids or pure liquids as either reactants or products. Understanding the equilibrium constant (k: units of k, we tend to use measured values of partial pressure and concentration to calculate for the equilibrium constant.
