MTEL Chemistry: Solutions - Chapter Summary
As you review for the Massachusetts Tests for Educator Licensure (MTEL) Chemistry exam, watch our professional instructors in this series of short, engaging lesson videos to improve your understanding of the components and properties of solutions. These lessons have been made to be mobile device compatible so that you may have a versatile way to review:
- Factors that contribute to the rate of dissolution
- Electrolytes, solutions, solubility and solubility curves
- Predicting reaction outcomes
- The solubility of common salts and gases
- Calculations for molarity and molar mass
- Finding the dilution of a solution
- Raoult's Law
Each of the lessons is brief, and they feature animation and graphics. Developed by chemistry experts, they're designed to remind you of topics you've previously studied as you get ready for the exam. Following your exploration of these lesson videos, use the lesson transcripts to study the vocabulary terms of the chapter.
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 the abbreviations and meaning of molarity and molality. Then apply what you have learned by going over some sample calculations with given concentrations.
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. 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.
