I cannot find the solubilities of iron. Iron sulfate ended up in my mescaline sulfate/water solution and crystallized out with it. The only information on iron sulfate solubility i found was that it is soluble in water which i already know and that iron carbonate/hydroxide is insoluble in water which i assumed. If i knew more about irons solubility in different forms i would isolate my mescaline. Can anybody more chem savvy impart wisdom i can utilize? Thank you for all your time and consideration.
