Solubility chart

{{Short description|Chart describing whether ionic compounds dissolve or precipitate}} {{For|detailed information on exact solubility of compounds|solubility table}} 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.

==Chart== The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. {{cvt|25|C|K|2|disp=comma}}). "Soluble" means the ionic compound does not precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate. For compounds with multiple hydrates, the solubility of the most soluble hydrate is shown.

Some compounds, such as nickel oxalate, will not precipitate immediately even though they are insoluble, requiring a few minutes to precipitate out.<ref name="oxalate">{{cite journal |author1=J. A.
