1. 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.
2. Solutions, Solutes, and Solvents
Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.
3. 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.
4. Acids and Bases
Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.
5. How to Write and Balance Chemical Reactions
Halloween glo sticks, firecrackers, table salt and the transport of CO2 waste in the body - what do they all have in common? They are all made possible by chemical reactions.
6. Common Chemical Reactions and Energy Change
This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.
7. Redox (Oxidation-Reduction) Reactions: Definitions and Examples
This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.
8. Aqueous Solution: Definition, Reaction & Example
Rainwater, Gatorade, and orange juice. These are just a few great examples of aqueous solutions. Read on to learn about aqueous solutions and their reactions in the environment.
9. Concentration Gradient: Definition & Example
In this lesson, you'll learn about the concentration gradient and its processes, as well as about the two types of diffusion, passive and facilitative, that happen along the concentration gradient.
10. Conjugate Base: Definition & Overview
In this lesson, you'll learn about conjugate bases in chemistry and where they come from. You'll also learn about their relationship to acids and see how acid-base reactions work.
11. Denaturation of Protein: Definition & Causes
Proteins are found in all living organisms. Problems occur when proteins become denatured. In this lesson, you will learn about a change in proteins known as denaturation.
12. Endothermic Reaction: Definition & Example
Chemical reactions usually involve the exchange of energy in some form. In this lesson, you will learn about a type of reaction known as an endothermic reaction.
13. Weak Bases: Examples & Overview
Did you know household ammonia, which is used as a cleaning product, can be classified as a weak base? Continue reading to learn about weak bases and discover more examples of these type of chemical substances.
14. What is Nitric Acid? - Structure, Uses & Formula
In addition to its uses in chemical laboratories, nitric acid is utilized in fertilizer, rocket fuel, and metallurgy. In this lesson, we will discuss nitric acid and its different uses, as well as learn about its formula and structure.
