Solubility Table of Compounds in Water at Temperature

Water temperature can have a significant effect on the solubility of compounds. Refer to the chart below to find reference values per gram of common compounds and salts (with chemical formula) at six temperatures of 100 g of water from 0 degrees to 100 degrees Celsius. The content and density of the total solution at 20 degrees are also provided. This table complements our Solubility Rules & Chart and Miscibility Table.
