4 1. WHAT ARE SOLUTIONS OBJECTIVE: WHAT ARE THEY?
5 SOLUTIONS IMPORTANCE OF STUDYING SOLUTIONS BECAUSE MANY REACTIONS TAKE PLACE IN SOLUTIONS BECAUSE MIXING REACTANTS IN SOLID FORM OFTEN DO NOT RESULT IN REACTIONS. REACTIONS REQUIRE COLLISIONS AT THE ATOMIC/MOLECULAR LEVEL, AND IN THE SOLID STATE, THIS DOES NOT OCCUR AT A SIGNIFICANT RATE.
6 1. WHAT ARE SOLUTIONS? SOLUTIONS ARE HOMOGENOUS MIXTURES HOMOGENOUS VS. HETEROGENEOUS MIXTURE VS. COMPOUND
7 1. WHAT ARE SOLUTIONS Does not always involve liquids

57 5. COLLIGATIVE PROPERTIES OBJECTIVE: HOW ADDING THINGS TO WATER CHANGES WATER
58 5. COLLIGATIVE PROPERTIES MAIN IDEA: The properties of a solution are different from those of a pure solvent. When you add things, like solutes, to water, it changes the properties of the water!
59 SOME OF THESE DIFFERENCES ARE DUE TO THE PRESENCE OF SOLUTE PARTICLES IN THE SOLUTION.
60 5. COLLIGATIVE PROPERTIES COLLIGATIVE PROPERTIES = A PROPERTY OF A SOLUTION THAT DEPENDS ON THE CONCENTRATION OF THE SOLUTE PARTICLES.
61 5. COLLIGATIVE PROPERTIES COLLIGATIVE PROPERTIES = 1. Increases boiling temperature 2. Lowers freezing temperature
62 COLLIGATIVE PROPERTIES COLLIGATIVE PROPERTIES A PROPERTY OF A SOLUTION THAT DEPENDS ON THE CONCENTRATION OF THE SOLUTE PARTICLES. THE WORD COLLIGATIVE IS DERIVED FROM THE LATIN COLLIGATUS MEANING BOUND TOGETHER, SINCE THESE PROPERTIES ARE BOUND TOGETHER BY THE FACT THAT THEY ALL DEPEND ON THE NUMBER OF SOLUTE PARTICLES.
63 COLLIGATIVE PROPERTIES BOILING POINT ELEVATION THE DIFFERENCE IN TEMPERATURE BETWEEN THE BOILING POINTS OF A SOLUTION AND OF THE PURE SOLVENT. FREEZING POINT DEPRESSION IS THE DIFFERENCE IN TEMPERATURE BETWEEN THE FREEZING POINTS OF A SOLUTION AND OF THE PURE SOLVENT.
64 Symbol Formula 4. CONCENTRATION Molarity MOLALITY Units Example
65 4. Molarity CONCENTRATIONMOLALITY Symbol M m Formula Units M = mol L mol = mol of SOLUTE L = liters of solution m = mol kg mol = mol of SOLUTE kg = kilograms of SOLVENT Example 5 M, or 5 molar 5 m, or 5 molal

69 COLLIGATIVE PROPERTIES THE MAGNITUDE OF BP ELEVATION AND FP DEPRESSIONS IS PROPORTIONAL TO THE NUMBER OF SOLUTE PARTICLES DISSOLVED IN THE SOLVENT.
70 COLLIGATIVE PROPERTIES WOULD A DILUTE OR CONCENTRATED SODIUM FLUORIDE SOLUTION HAVE A HIGHER BOILING POINT? IF EQUAL NUMBER OF MOLES OF KI AND MGF 2 ARE DISSOLVED IN EQUAL AMOUNTS OF WATER, WHICH SOLUTION WOULD HAVE THE HIGHEST: BOILING POINT FREEZING POINT
71 MOLARITY MOLALITY VOLUME OF SOLUTE + VOLUME OF SOLVENT UNIT = M MASS OF SOLVENT IN KILOGRAMS UNIT = M (ITALICIZED) BOTH MOLARITY AND MOLALITY MEASURE
