Learn the solubility rules to predict precipitate formation. Included are memorization tips and a printable chart.
Review solubility rules for common ionic compounds in water, including calcium carbonate, barium sulfate, and sodium sulfate, using the provided chart.
In this article, we look at the common solubility rules of chemistry, which state which anions and cations are usually soluble, and which aren’t. We will also display a solubility chart that states the solubility of many common ionic compounds.
A solubility chart is a chart describing whether the ionic compounds formed from different combinations of cations and anions dissolve in or precipitate from solution.
When a substance is mixed with a solvent, there are several possible results. The determining factor for the result is the solubility of the substance, which is defined as the maximum possible concentration of the solute. The solubility rules help determine which substances are soluble, and to what extent.
What are the chemistry solubility rules? Check out our solubility rules chart and complete guide to these important principles.
What are solubility rules. Learn which compounds are soluble and which are not. Check out the solubility rules chart.
Every ion is a spectator ion and there is no net ionic equation at all. It is useful to be able to predict when a precipitate will occur in a reaction. To do so, you can use a set of guidelines called the solubility rules (Tables \(\PageIndex{1}\) and \(\PageIndex{2}\)).
Solubility Rules Chart. If you want to determine the solubility of a compound, start by writing out its empirical formula. This will help you identify each of the ions that make it up. You can then use either solubility rules or a solubility chart to check the compound's solubility.
Determine the solubility of common ionic compounds. When some substances are dissolved in water, they undergo either a physical or a chemical change that yields ions in solution. These substances constitute an important class of compounds called electrolytes .
