About This Chapter
Properties of Solutions in Chemistry - Chapter Summary
Increase your ability to define specific terms and understand formulas relevant to laws and properties of solutions with this short chapter. Lessons simplify this material through illustrations and examples that clarify complex topics.
Study of these lessons will help you identify and explain such terms and phrases as osmosis, freezing point depression and molecular weight. Once you have completed your review of this chapter, you should be able to:
- Calculate the concentration and boiling-point elevation of a solution
- Define terms such as 'saturated', 'unsaturated' and 'supersaturated'
- Explain the meaning of freezing point depression
- Apply the formula for determining molecular weight
- Describe osmosis and osmotic pressure
Experienced instructors will easily guide you through this complex material to ensure your full understanding as you move from one lesson to the next. Test your knowledge of each topic with a self-assessment quiz at the end of each lesson and track your progress using your Dashboard. Lessons are accessible from any device 24/7, so you can study when it's most convenient for you.
1. Concentration of Solutions: Definition & Levels
In this lesson, we learn about solutions and what makes up a solution. We also look at solution concentration levels and how to calculate the concentration of a solution.
2. Solubility and Solubility Curves
Solubility refers to a solute's ability to dissolve; a solubility curve is defined as the relationship between a solute's solubility and the temperature. Learn to use solubility curves to identify and understand the differences among saturated, unsaturated, and supersaturated solutions.
3. Freezing Point Depression: Definition, Equation & Examples
In this lesson, we will describe what it means to have a freezing point depression. We will explain how we determine the new freezing point and show examples of when this is used in the world.
4. Calculating Boiling-Point Elevation of a Solution
Electrolytes are ionic compounds that can complicate the boiling-point elevation equation. Discover how to calculate the boiling-point elevation of any solution through equations, examples, background, and review in this lesson.
5. Molecular Weight: Definition & Formula
In this lesson, we will learn about molecular weight, which is the mass of a molecule determined by summing the masses of all of the atoms that make it up. We will look at the formula for determining molecular weight, learn where to find atomic masses on the periodic table, and do an example calculation.
6. Osmosis: Definition & Examples
Osmosis is a form of diffusion in which a higher concentration gradient travels across a semi-permeable membrane to a lower concentration gradient. Learn about the definition/examples of osmosis, the types of solutions, and how osmosis changes cell volume.
7. Osmotic Pressure: Definition & Formula
Osmotic pressure is created by the movement of water across a membrane through the process of osmosis. Learn the definition of osmotic pressure and the formula used to calculate it, and practice using it by solving practice problems.
