In these reactions, one atom loses electrons (oxidation) while another element gains those electrons (reduction), making them a form of a redox reaction. Learn to use the Activity Series, which ranks elements by their reactivity and helps predict if the reaction will occur.

The driving force in these reactions is often the formation of a precipitate, a gas, or water. A solubility chart is commonly used to predict whether a potential product will be insoluble and therefore precipitate out of solution. This allows us to determine if the reaction will actually occur.
