I'm having issues dissolving LiOH in deionised water and it won't fully dissolve.
I'm working up a reaction that requires mole ratio values of 1 : 3 for FeSO4.7H2O : LiOH.H2O in 50 mL of water, whilst maintaining the reaction concentration of FeSO4 at 0.5 M. To do this, 3.147 g of LiOH.H2O is needed.
SigmaAldrich states the published water solubility of this to be 200 g/L at 20 °C. I have tried warming the water, leaving it stirring over the weekend, using a different supplier of LiOH.H2O and it still fails to dissolve.
Previously an organic chemist now working on inorganics, not sure if I have missed out something regarding the theory etc?
Any suggestions are greatly appreciated
