  • Oxidation-Reduction reactions
  • How to write and balance chemical reactions
  • Weak acids, weak bases and buffers

We offer many tools to help you prepare for the ILTS Biology exam. Our lessons average about six minutes each, and you can watch them as your schedule allows, using our dashboard feature to help keep track of your progress. Every lesson includes a clickable timeline that makes it easy to return to the lesson and review specific areas.

ILTS Biology: Inorganic Chemistry Chapter Objectives

In Illinois, passing the ILTS Biology exam is one of the requirements for certification to teach the subject. The ILTS Biology exam contains 125 multiple-choice questions, divided into six subareas. You can practice answering questions in this format by taking the quizzes that accompany each of our lessons. These quizzes also offer a good opportunity to assess your learning and find out your weaknesses before exam day. Wrong answers come with a link that lets you jump right back to the pertinent point in the lesson.

The Foundational Elements of Life

1. The Foundational Elements of Life

Living things are complex products of their environments. They are made of a number of different natural elements, many of which are essential to survival. Because of this, they are considered foundational elements and they support life on Earth as we know it.

The Atom

2. The Atom

Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?

Properties of Water

3. 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.

Solutions, Solutes, and Solvents

4. 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.

Osmosis, Diffusion and Saturation

5. 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.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

6. 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.

Basic Properties of Chemical Reactions

7. Basic Properties of Chemical Reactions

Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.

Weak Acids, Weak Bases, and Buffers

8. Weak Acids, Weak Bases, and Buffers

This lesson covers both strong and weak acids and bases, using human blood as an example for the discussion. Other concepts discussed included conjugate acids and bases, the acidity constant, and buffer systems within the blood.
