Ch 21: ILTS Biology: Acids, Bases & Chemical Reactions

About This Chapter

Brush up on your understanding of acids and bases and various types of chemical reactions as you study fro the ILTS Biology exam. Our lively lessons and brief quizzes can prepare you to correctly answer exam questions on these topics.

ILTS Biology: Acids, Bases & Chemical Reactions - Chapter Summary

The lessons in this chapter aid you in reviewing information on the properties of acids and bases and chemical reactions involving them. Watching these videos can help you answer ILTS Biology exam questions on the following topics:

  • Definition of bases and acids
  • Decomposition, synthesis and neutralization of reactions
  • Dissociation constant and autoionization of water
  • Acid and base anhydrides
  • The pH scale, solutions and buffers
  • Coordination chemistry
  • Precipitation reactions
  • How to balance redox reactions
  • The activity series
  • Electrochemistry
  • How to write and balance combustion reactions

Our study guide provides a number of ways to help you prepare for the ILTS Biology exam, including a personalized dashboard feature that shows your progress through the lessons. You can use our message board to ask questions of the instructors and use the clickable timelines to quickly locate parts of the video lesson you'd like to review.

ILTS Biology: Acids, Bases & Chemical Reactions Chapter Objectives

In Illinois, one of the requirements for licensing to teach biology is passing the ILTS Biology exam. This 125-question exam is divided into six subareas. Questions on the material in this chapter would be in the Physical Science subarea.

All exam questions are multiple choice, like the questions on the lesson quizzes in this chapter. These quizzes show you what answering questions in this format will be like. Taking the quizzes also lets you evaluate your knowledge and see where you need extra study before exam day.

Acids and Bases

1. 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.

Decomposition and Synthesis Reactions

2. Decomposition and Synthesis Reactions

Learn how to write, identify and predict the products of simple synthesis and decomposition reactions. This includes the composition of reactions with oxygen, of two metals, and of metals with nonmetals, as well as the decomposition of metal carbonates, metal chlorates and metal hydroxides.

Dissociation Constant and Autoionization of Water

3. Dissociation Constant and Autoionization of Water

Learn the meaning of auto-ionization of water, sometimes called self-ionization, where water acts as a proton donor and acceptor to form both hydronium and hydroxide ions. Learn what the auto-ionization constant is and how to use it to determine the concentration of either hydroxide or hydronium ions in a solution when given the other value.

The pH Scale, Solutions & Buffers

4. The pH Scale, Solutions & Buffers

What do lemons, drain cleaner and blood have in common? They are either acids or bases. This lesson will explore acids and bases, giving examples and definitions. It will also explain how to calculate the pH and the pOH, and will define buffers.

Acid & Base Anhydrides: Definition & Examples

5. Acid & Base Anhydrides: Definition & Examples

In this video lesson, you will learn the definition and the types of anhydrides that form acids and bases in water. You will also discover where you can commonly find anhydrides and why they are important. A short quiz will test your knowledge.

Coordination Chemistry: Bonding in Coordinated Compounds

6. Coordination Chemistry: Bonding in Coordinated Compounds

Discover what a coordinated compound is. Understand how bonding occurs in coordinated compounds and some of the possible shapes coordinated compounds can be. Learn the uses in nature and industry for coordinated compounds.

Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

7. 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.

Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents

8. Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents

Learn how to identify an oxidizing agent and a reducing agent and how the loss or gain of electrons applies to each one. Learn the relationship between an oxidized or reduced substance and the oxidizing or reducing agent associated with it. Discover what steps to take to balance a redox reaction.

The Activity Series: Predicting Products of Single Displacement Reactions

9. The Activity Series: Predicting Products of Single Displacement Reactions

Discover what a single replacement reaction is and how to identify it. Learn what chemical activity is, how that applies to an activity series table and how to predict the product of a single replacement reaction by referring to the activity series.

Electrochemical Cells and Electrochemistry

10. Electrochemical Cells and Electrochemistry

Learn to identify the parts of and be able to describe an electrochemical cell, including the electrolyte, electrodes, anodes, and cathodes. Learn how to make a homemade lemon battery and how to diagram an electrochemical cell that will light a light bulb.

Cathode and Anode Half-Cell Reactions

11. Cathode and Anode Half-Cell Reactions

Learn how to write electrode half-reactions for cathodes and anodes. Discover how to calculate cell voltage potential when given a table of standard electrode potentials. Learn how to prevent corrosion using redox concepts and how to protect metal by cathodic protection.

Writing and Balancing Combustion Reactions

12. Writing and Balancing Combustion Reactions

Discover what a combustion reaction is as well as what reactants are needed and what products are produced. Learn to write and balance a combustion reaction. Through the concepts of bond energies, learn how to explain why combustion reactions are largely exothermic.
