Solubility chart

A solubility chart refers to a chart with a list of ions and how, when mixed with other ions, they can become precipitates or remain aqueous. The following chart shows the solubilities of various compounds at a pressure of 1 atm and at room temperature (approx. 293.15 K). Any box that reads "soluble" results in an aqueous product, while "slightly soluble" and "insoluble" markings means that there is a precipitate that will form (usually, this is a solid). Boxes marked "other" can mean that many different states of products can result. For more detailed information of the exact solubility of the compounds, see the solubility table.

The chemicals have to be exposed to their boiling point to fully dissolve.
