Students will review:
This chapter helps students review the concepts in an Elements, Compounds, Mixtures & Solutions unit of a standard college physical science course. Topics covered include:
- Use of colligative properties to determine molar mass
- The rate of dissolution
- Solubility and solubility curves
- Elements and compounds
- Covalent and ionic compounds
1. 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.
2. 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.
3. 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.
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.
5. 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.
6. 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.
7. 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.
8. Chromatography, Distillation and Filtration: Methods of Separating Mixtures
What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.
9. What Are Elements?
Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.
10. Covalent Compounds: Properties, Naming & Formation
Learn about covalent bonds, how covalent compounds are formed and the properties inherent to covalent compounds, such as low melting and boiling points, in this lesson. Also, learn what rules to follow to name simple covalent compounds.
11. Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds
An important part of dealing with chemical compounds is knowing how to refer to them. Learn how to name all ionic compounds, including simple binary compounds, compounds containing transition metals and compounds containing polyatomic ions.
12. Ionic Compounds: Formation, Lattice Energy and Properties
In this lesson, you'll learn about ionic compounds and how they form. Additionally, you'll learn the properties of ionic compounds, such as their high melting and boiling points, their ability to conduct electricity, and the fact that they form crystals.
13. Potassium Dichromate: Definition, Formula & Uses
Did you know another name for potassium dichromate is hexavalent chromium? In this lesson, we will learn why potassium dichromate has a second name, understand its formula, and discover where it is used.
14. Meso Compound: Definition & Examples
In chemistry, there are compounds that are symmetric when you divide them down the middle. These compounds are called meso compounds. In this lesson, we'll learn about meso compounds and how to identify them.
15. What Are Polymers? - Properties, Applications & Examples
Polymers are huge molecules that are encountered in nature as well as in our modern technology. This lesson introduces students to polymers, their properties, and some of the many ways polymers are found in the modern world.
