1 WHAT IS A SOLUTION? PROPERTIES OF SOLUTIONS BRAINSTORM: What do you already know about solutions? CH. 13 Possible answers SOLUTION TYPES Homogeneous Composed of solute and solvent Solvent is commonly the component in greatest amount Solutions can be in any state of matter 1
2 Solution A homogeneous mixture of two or more substances in a single phase. Does not have to involve liquids -- air is a solution of nitrogen, oxygen, carbon dioxide etc.; solder is a solution of lead, tin etc. Solute Component in lesser amount. Dissolvee Solvent Component in greater amount; Component whose phase is the phase of the solution; Water. Dissolver Maximum amount of material that will dissolve in a given amount of solvent at a given temp. to produce a stable solution. Solubility 2
3 Saturated Solution A solution containing the maximum amount of solute that will dissolve under a given set of conditions. Saturated solutions are at dynamic equilibrium with any excess undissolved solute present. Solute particles dissolve and Re-crystallize at equal rates. This point is the same as solubility for that substance. Unsaturated Solution A solution containing less than the maximum amount of solute that will dissolve under a given set of conditions. (more solute can dissolve) Supersaturated Solution A solution that has been prepared at an elevated temperature and then slowly cooled. It contains more than the usual maximum amount of solution dissolved. 3
4 A supersaturated solution is very unstable and the addition of a seed crystal will cause all excess solute to crystallize out of solution leaving the remaining solvent saturated. (rock candy is made this way) The beaker on the left holds a simple binary (2 components) aqueous solution. Describe an experiment that could determine whether the solution is saturated, unsaturated or supersaturated. Miscible When two or more liquids mix. (example: Water and food coloring) Immiscible When two or more liquids DON T mix.--they usually layer if allowed to set for a while. (example: Water and oil) 4
5 THE SOLUTION PROCESS Energies Involved in Solution Formation When a solute is dissolved in a solvent, the attractive forces between solute and solvent particles are greater compared to the attractive forces within the pure solvent and solute. The solute becomes solvated (usually by dipole-dipole or iondipole forces). When the solvent is water, the solute is hydrated. Like Dissolves Like Substances with similar types of intermolecular forces dissolve in each other. Water dissolves many salts because the strong ion-dipole attractions that water forms with the ions are very similar to the strong attractions between the ions themselves. Polar solvents dissolve polar or ionic solutes. Nonpolar solvents dissolve nonpolar solutes. 5
6 The same salts are insoluble in hexane (C 6 H 14 ) because the weak LDF forces their ions could form with this nonpolar solvent are much weaker than the attraction between ions. Why doesn t oil dissolve in water? Oil does not dissolve in water because the LDF-dipole forces are much weaker than the hydrogen bonding of water. Heat of Solution (ΔH soln ) The enthalpy change associated with the formation of a solution. 3 steps: ΔH soln = ΔH 1 + ΔH 2 + ΔH 3 (Just the sum of all of the steps involved!) Let s take a look. 6
7 Step 1 (ΔH 1 ) Breaking up solute (endothermic), expanding the solute. High in ionic and polar solutes, low in nonpolar solutes ΔH soln can be positive (endothermic) or negative (exothermic). ΔH solute = -ΔH lattice energy Step 2 (ΔH 2 ) Breaking up solvent (endothermic), expanding the solvent. High in polar solvent, low in nonpolar solvent. Step 3 (ΔH 3 ) Interaction of solute and solvent (exothermic). High negative in polar-polar, low negative in rest. 7
8 ΔH 2 + ΔH 3 Enthalpy of Hydration ΔH hyd Entropy Change Exothermic enthalpy always favor solution formation. Endothermic solution process may or may not. Entropy is the decider ΔS soln usually positive. If solution process is VERY endothermic, no solution formed. Summarizing: Solubility generally increases with temperature if the solution process is endothermic (ΔH soln > 0). Enthalpy of hydration is more negative for small ions and highly charged ions. Solubility generally decreases with temperature if the solution process is exothermic (ΔH soln < 0). 8
9 Exercise 3 Decide whether liquid hexane (C 6 H 14 ) or liquid methanol (CH 3 OH) is the more appropriate solvent for the substances grease (C 20 H 42 ) and potassium iodide (KI). hexane grease methanol KI Solution Factors Affecting Solubility Molecular Structure Fat Soluble Vitamins A, D, E, & K - Nonpolar Can be stored in the body tissue such as fat. 9
10 Water Soluble Vitamins B & C - Polar Are not stored, must be consumed regularly. Hydrophobic and Hydrophilic Phobic=Water fearing;nonpolar Philic = Water loving; Polar Solids and Solubility Earlier we discussed temperature and its effect with solids in solution. What is the general trend? Network solids Name a few Generally, insoluble can you explain this? What are the 4 general types of solids? 10
11 Molecular solids Name one common molecular solid. Generally, these are very soluble..explain. Name several.. Metallic solids What would you expect the solubility to be in water? Why? What is an alloy? How does this happen? Name one. Ionic solids Name a few. Generally, these solid substances are soluble. How can this be? Solubility of Gases Generally, as the temperature increases, the solubility of a gas decreases. 11
12 Can you explain this on the molecular level? Henry s Law The amount of a gas dissolved in a solution is directly proportional to the pressure of the gas above the solution. 12
