TExES Chemistry: Acids, Bases & Chemical Reactions - Chapter Summary
Use the lessons in this chapter to assess your knowledge of definitions, calculations and chemical processes relating to acids and bases. The lessons also cover various types of chemical reactions and the equations used to represent them. After viewing these lessons, you should be prepared to answer relevant questions on the TExES Chemistry 7-12 exam by demonstrating the following:
- Understanding definitions of acids and bases
- Describing various types of chemical reactions, such as synthesis reactions, precipitation reactions, combustion reactions and redox reactions
- Calculating pH
- Providing details about coordinated compounds
- Defining electrochemistry and electrochemical cells
- Detailing the process of corrosion
Complex topics are discussed using simple and direct language, and the short videos include examples and illustrations. Self-assessment quizzes accompanying each lesson provide you with the opportunity to assess your knowledge; you can choose to take the quizzes both before and after viewing the lessons.
TExES Chemistry: Acids, Bases & Chemical Reactions Objectives
The Acids, Bases & Chemical Reactions chapter is designed to cover what you'll need to know to answer questions found in the third domain of the TExES Chemistry 7-12 exam. The lessons address relevant chemical models, properties and relationships of acids and bases as well as analyses of various chemical reactions. This domain accounts for 23% of the entire computer-based test, which consists of 100 multiple-choice questions.
TExES are teacher certification exams used in the state of Texas. These are used to assess an entry-level educator's knowledge of areas in which they are seeking to teach. Exams are given in various content areas, ranging from art to speech, as well as core subjects. You will be required to score at least a 240 in order to pass any TExES exam.
1. The Arrhenius Definition of Acids and Bases
In this lesson, you will learn the definition of Arrhenius acids and bases, discover some of their chemical properties and learn some examples. You will also learn about the difference between strong and weak Arrhenius acids and bases.
2. The Bronsted-Lowry and Lewis Definition of Acids and Bases
Learn the Bronsted-Lowry and Lewis definitions of an acid and base. Discover how these theories differ from each other and from the Arrhenius theory of an acid and base. Learn how to identify an acid in terms of proton donation and a base as a proton acceptor, and explain what a conjugate acid or base is.
3. 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.
4. 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.
5. The pH Scale: Calculating the pH of a Solution
Learn the history of the pH scale, how to describe it and why it is used by scientists. Discover how to calculate the pH of an acid or base solutions given either the hydroxide ion concentration or the hydronium ion concentration. Learn how to start with the pH and calculate the hydroxide and hydronium ion concentrations.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. What is Salt in Chemistry? - Definition & Formula
What exactly do we mean by 'salt' in chemistry? Learn more about the definition, chemical, and physical properties and how we can easily figure out the chemical formula of many salts. Test what you have learned with a quiz.
