- 5.1: Chemical Equations
- To simplify the writing of reactions, we use formulas instead of names when we describe a reaction. We can also use symbols to represent other words in the reaction.
- 5.2: Balancing Chemical Equations
- Chemical reactions are represented by chemical equations that list reactants and products. Proper chemical equations are balanced; the same number of each element’s atoms appears on each side of the equation.
- 5.3: Acids, Bases, and Neutralization Reactions
- An acid is any compound that produces hydrogen ions (H+) in an aqueous solution, and the chemical opposite of an acid is a base, which is a compound that produces hydroxide ions (OH−) in an aqueous solution.
- 5.4: 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.
