Students will review:
This chapter helps students review the concepts in a solutions unit of a standard AP chemistry course. Topics covered include:
- The rate of dissolution
- Electrolytes and nonelectrolytes
- Effects of pressure and temperature on solubility
- Molarity and molality concentration calculations
- Molar mass determination through the use of colligative properties
- Solubility of gases
1. The Rate of Dissolution: Factors and Definition
Learn what dissolution is and the factors that affect the rate of dissolution, such as temperature, surface area, polarity and pressure. Learn what miscible and immiscible mean in regards to liquids.
2. Solutions, Electrolytes and Nonelectrolytes
Learn what a solution is and how it is formed. Learn how to express the concentration of a solution in terms of molarity, molality and mass percent. Discover the differences between an electrolyte and a nonelectrolyte.
3. Solubility and Solubility Curves
Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.
4. Solubility of Common Salts: Predicting Reaction Outcomes
Ever wondered why some salts dissolve in water and others don't? In this lesson you will learn about some simple salt solubility rules. Using these rules, you will be able to predict the products of many chemical reactions.
5. Calculating Molarity and Molality Concentration
Learn what molarity and molality are and how to calculate each one. Learn that molarity is abbreviated as M and is moles of solute per liter of solution and that molality is abbreviated as m and is moles of solute per kilogram of solvent.
6. Calculating Dilution of Solutions
Learn what a solution is and how to properly dilute a new solution from a stock solution. Learn the dilution equation that combines molarity, the volume of stock solution and desired solution to determine how much stock solution is needed for the new solution.
7. Colligative Properties and Raoult's Law
Learn how vapor pressure and osmotic pressure are colligative properties. Learn Raoult's Law and how to use it to determine the vapor pressure of a solution. Learn the equation for determining osmotic pressure and how to use it to determine the molar mass of a substance.
8. Using Colligative Properties to Determine Molar Mass
In this lesson, we will explore the effect of colligative properties on a solution. We will learn how to calculate freezing point depression and see how it can be used to calculate the molar mass of an unknown substance.
9. Isotonic Solution: Definition & Example
An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side.
10. The Solubility of Gases in a Liquid
In this video lesson, you will learn what solubility is and the factors that affect gas solubility. We will use real-life examples to illustrate the importance of understanding solubility. A quick quiz will then test our new knowledge.
