Reduction in Chemistry: Definition & Overview

1. Reduction in Chemistry: Definition & Overview

When atoms are greedy for electrons, they steal them from other atoms. This reduces their charge. You can see the effects of reduction in the world around you. Learn more about reduction in chemistry and see some examples of it.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

2. 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.

Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents

3. 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

4. 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

5. 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

6. 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

7. 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.
