WebWater 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. Some iron(III) salts, like the chloride FeCl3, sulfate Fe2(SO4)3, and nitrate Fe(NO3)3 are soluble in water. However, other compounds like oxide Fe2O3 (hematite) and iron(III) oxide-hydroxide FeO(OH) are extremely insoluble, at least at neutral pH, due to their polymeric structure. Therefore, those soluble iron(III) salts tend to hydrolyze when dissolved in pure water, producing iron(III) hydroxide Fe(OH)3 that immediately converts to polymeric oxide-hydroxide via the process called
