Students will review:
This chapter helps students review the concepts in a Solutions unit of a standard college-level general chemistry course. Topics covered include:
- Solubility and solubility curves
- Calculating molarity and molality concentration
- Calculating dilution of solutions
- Determining molar mass using colligative properties
- Colligative properties and Raoult's law
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. Calculating Molarity and Molality Concentration
Learn the abbreviations and meaning of molarity and molality and go over some sample calculations with given concentrations.
5. 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.
6. 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.
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. Hypotonic Solution: Definition, Example & Diagram
A hypotonic solution is any solution that has a lower osmotic pressure than another solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.
9. Unsaturated Solution: Definition & Examples
In this lesson, you''ll learn the definition of an unsaturated solution. There will be examples provided to assist you with your understanding of the topic. Also, several examples of unsaturated solutions are provided.
10. What is a Solution in Science? - Definition & Examples
The air we breathe, what we drink, as well as products in our household - these are a few examples of solutions we encounter every day. In this lesson, we will discuss what a solution is, the different types, as well as examples.
11. Standard Solution: Definition & Method
In this lesson, learn about standard solutions and the characteristics that define them. Explore what they are, as well as learn the method behind how to make one.
12. Acidophiles: Definition & Example
Have you ever heard of a microbial organism called an acidophile? Continue this lesson to learn about this fascinating microorganisms, their relationship to acidity, and their importance to our ecosystem.
13. Molecular Substance: Definition & Properties
Hydrogen peroxide, water, and carbon dioxide all have something in common: They are examples of molecular substances. Discover what a molecular substance is, and learn about the different properties used to define these compounds.
