Decomposition and Synthesis Reactions

1. 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.

The Arrhenius Definition of Acids and Bases

2. 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.

The Bronsted-Lowry and Lewis Definition of Acids and Bases

3. 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.

Neutralization and Acid-Base Reactions

4. Neutralization and Acid-Base Reactions

From this lesson, you will understand the neutralization process between acids and bases. Learn how a hydroxide ion from a base reacts with a hydronium ion from an acid to neutralize each other and form water. Discover what conjugate acids and bases are and what the definition of amphoteric is.

Dissociation Constant and Autoionization of Water

5. 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: Calculating the pH of a Solution

6. 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.

Coordination Chemistry: Bonding in Coordinated Compounds

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.

Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

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.

Assigning Oxidation Numbers to Elements in a Chemical Formula

9. Assigning Oxidation Numbers to Elements in a Chemical Formula

Learn the importance of oxidation in chemical reactions. Discover the rules for assigning oxidation numbers in both covalent compounds and ionic compounds. Learn how to assign the oxidation number for each element in a chemical formula.

Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents

10. 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

11. 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

12. 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

13. 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

14. 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.

Cathode Ray Experiment: Summary & Explanation

15. Cathode Ray Experiment: Summary & Explanation

Learn about the Cathode Ray Experiment, one of the most important discoveries of the atomic physics era. Learn how it helped physicist J.J. Thomson's discovery of a previously unidentified subatomic particle.

Electrodes: Definition & Types

16. Electrodes: Definition & Types

An electrode is a pretty versatile material - you can find one in your non-rechargeable battery or an electrolytic cell. Continue reading to learn about the two types of electrodes - anodes and cathodes - and how they function in electrical devices.

Bronsted-Lowry Base: Definition & Examples

17. Bronsted-Lowry Base: Definition & Examples

There are different definitions of bases from different scientists, so what classifies a solution as basic? In this lesson, we will learn about the definition of a basic solution proposed by two scientists, Bronsted and Lowry.
