Aim: How can you determine how much solute a solvent can hold? QQ: You dissolve 20.0 g of NaCl in enough water to make 1.0 L of solution. What is the solution concentration in molarity? Do Now: What three “states” can a solution exist in? Solution “States” Unsaturated: The solvent is able to hold more solute Solid dissolves when added to the solvent Saturated: Solvent cannot hold anymore solute Additional solute will not dissolve Exists at equilibrium Supersaturated: Solvent is holding more solute than it should be able to under the given conditions Adding more solute causes the excess solute to “crash” out of solution Artificially induced, delicate state Solubility The amount of solute that can be dissolved in a solvent depends on 3 different factors: Temperature Pressure Phase of the solute Solids High temperatures increase solubility Pressure has virtually no effect Gases
