- 6.9: Some Types of Chemical Reactions
- Although there are untold millions of possible chemical reactions, most can be classified into a small number of general reaction types. Classifying reactions has two purposes: it helps us to recognize similarities among them, and it enables us to predict the products of certain reactions. A particular reaction may fall into more than one of the categories that we will define in this book.
- 6.10: Oxidation-Reduction (Redox) Reactions
- Chemical reactions in which electrons are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.
- 6.11: Redox Reactions in Organic Chemistry and Biochemistry
- Redox reactions are common in organic and biological chemistry, including the combustion of organic chemicals, respiration, and photosynthesis.
- 6.13: Double Replacement Reactions
- A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds.
