Solutions

Objectives

• Identify the factors that determine the rate at which a solute dissolves
• Identify the units usually used to express the solubility of a solute
• Identify the factors that determine the mass of solute that will dissolve in a given mass of solute

Vocabulary: saturated solutions - solubility - unsaturated solution - miscible - immiscible - supersaturated solution - Henry's Law

Objectives

• Solve problems involving the molarity of a solution
• Describe the effect of dilution on the total moles of solute in solution
• Define percent by volume and percent by mass solutions

Vocabulary: concentration - dilute solution - concentrated solution - molarity (M)

Objectives

• Identify three colligative properties of solutions
• Explain why the vapor pressure, freezing point, and boiling point of a solution differ from those properties of pure solvent
• Solve problems related to the molality and mole fraction of a solution
• Describe how freezing point depression and boiling point elevation are related to molality

Vocabulary: colligative property - freezing point depression - boiling point elevation - molality (m) - mole fraction
