Chem 110 Recitation 12 Page 1 CHEM 110 – Recitation 12 Learning Objectives Factors that affect Solubility Know the expected behavior of the solubility of salts in water as a function of temperature. Know the trend in solubility of gases like N 2 and O 2 in water as a function of temperature. Understand what is meant by: Like dissolves like. Be able to predict the relative solubility of solutes in a solvent by applying the concept of like dissolves like. Be able to predict which solvent would be able to dissolve a given solute by applying the concept of like dissolves like. Know the relationship between gas solubility and pressure (Henry’s Law). C g = K H P g Be able to apply Henry’s law to quantitatively determine the solubility of gases in a dilute solution. Colligative properties Know what is meant by a colligative property.

Unformatted text preview: Know qualitatively what will happen to vapor pressure, boiling point, melting point and osmotic pressure of a solution upon addition of a solute. Be able to calculate the vapor pressure of a dilute solution using Raoults Law. P A = X A P A Know the normal boiling point and melting point of water. Be able to calculate the boiling point or melting point of a solution given the boiling point and /or melting point constants and the normal boiling and melting points of the solvent. T b = K b m given K b T f = K f m given K f Know what osmotic pressure is. Know how to calculate the osmotic pressure of a solution. = MRT Be able to find the molecular weight of a solute from measurements of one of the colligative properties....
