Double replacement reactions occur when two compounds exchange ions, forming two new compounds. 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.
