7 Lessons in Chapter 6: Physical Science - Understanding Solutions: Homework Help
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.

Solubility of Common Salts: Predicting Reaction Outcomes

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.

Calculating Molarity and Molality Concentration

5. Calculating Molarity and Molality Concentration

Learn what molarity and molality are and how to calculate each one. Learn that molarity is abbreviated as M and is moles of solute per liter of solution and that molality is abbreviated as m and is moles of solute per kilogram of solvent.

Calculating Dilution of Solutions

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.

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.
