Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids. Because not all aqueous reactions form precipitates, one must consult the solubility rules before determining the state of the products and writing a net ionic equation.

It defines suspensions as heterogeneous mixtures where larger particles settle, contrasting them with solutions. Examples like milk and water-based paint are provided, highlighting the need for stirring to keep suspended particles evenly distributed.
