Question 1
1. What is the molality of a solution of 5.00 g of tridecanoic acid dissolved in 20.0 g of stearic acid? 2. Calculate the observed change in the freezing point (AT:) from pure stearic acid to the mixture described in question 1. 3. Do colligative properties depend on the number of particles dissolved, the identity of the particles dissolved, or both? 4. Find the SDS for stearic acid. What hazards are associated with stearic acid? Terms You Should Know A solution is a mixture of a solvent (the more abundant chemical) and a solute (the less abundant chemical). Colligative Properties, such as vapor pressure lowering, freezing point depression, boiling point elevation, and osmotic pressure, are properties that depend on the concentration of solute in solution, but not on the identity of the solute.
