About This Chapter
Solution Types & Properties - Chapter Summary
This chapter looks at a variety of solution types and properties. It includes lessons that touch on related chemical principles, terms, and other concepts important to know when studying solutions. The topics discussed in this chapter include:
- The impact of osmosis, diffusion and saturation on cells
- The frequency of dissolution
- Molarity and molality concentration
- Precipitation reactions
- Colligative and water properties
- Raoult's law
- Distinguishing between electrolytes and non-electrolytes
You'll be able to pick between a video and transcript of each lesson, depending on your learning preference. The timeline feature underneath the videos allows you to jump around main points of the material, while the transcripts come loaded with key terms and topics pointed out in bold print.
1. Osmosis, Diffusion and Saturation
The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.
2. 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.
3. 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.
4. Precipitation Reactions: Predicting Precipitates and Net Ionic Equations
Learn what a precipitate is and predict when it will form in an aqueous chemical reaction, usually a double-replacement reaction. Learn what an ionic equation is, how it differs from a net ionic equation and how to write a net ionic equation.
5. 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.
6. 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.
7. Properties of Water
Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.
