Solubility chart

From Wikipedia, the free encyclopedia
Jump to: navigation, search

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.
