Ch 8: Solutions: Help and Review

About This Chapter

The Solutions chapter of this College-Level General Chemistry Help and Review course is the simplest way to master solutions. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of solutions.

Who's it for?

Anyone who needs help learning or mastering college-level general chemistry material will benefit from taking this course. There is no faster or easier way to learn college-level general chemistry. Among those who would benefit are:

  • Students who have fallen behind in understanding the rate of dissolution or working with solutions, electrolytes and nonelectrolytes
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about solutions
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Solutions chapter exam.

Why it works:

  • Study Efficiently: Skip what you know; review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Solutions chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any solutions question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

The Rate of Dissolution: Factors and Definition

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.

Solutions, Electrolytes and Nonelectrolytes

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.

Solubility and Solubility Curves

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.

Calculating Molarity and Molality Concentration

4. 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.

Calculating Dilution of Solutions

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.

Using Colligative Properties to Determine Molar Mass

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.

Colligative Properties and Raoult's Law

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.

Hypotonic Solution: Definition, Example & Diagram

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.

Unsaturated Solution: Definition & Examples

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.

What is a Solution in Science? - Definition & Examples

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.

Standard Solution: Definition & Method

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.

Acidophiles: Definition & Example

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.

Molecular Substance: Definition & Properties

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.
