Producing Calcium nitrate from ammonium nitrate and calcium hydroxide is a rather irritating task to do so I'm trying to find an alternative
method. According to someone on a different board Ca(NO3)2 is soluble in acetone but KNO3, KCl, and CaCl2 aren't. Thus Ca(NO3)2 could be made by
dissolving stoichiometrical amounts of KNO3 and CaCl2 in water, then after evaporating the water dissolve the Ca(NO3)2 into acetone. I guess that
method is still a bit of work but it is less annoying then having to boil a Ca(OH)2 and NH4NO3 solution for a long time. Anyway I just figured
I'd check here to ensure that those solubilities and insolubilities in acetone are correct.

Would you like me to try and look up my sources again? There were at least two for each chem. so it may take a while. I think you could also just
look up the electronegitivity values for each one and see. I don't recall where acetone starts to dissolve in EN values. Perhaps someone else
would know.

Where do you get the info on different solubilities anyway? I can never find anything but solubility in water and occasionally solutbility in alcohol
when searching online.

Well the Calcium Nitrate solubility in acetone is in some msds I found, and product specification sheets I found:

The rest I basically search around for and get lucky. Most of the time I can't fine solubility in specific compounds, besides water or alcohol,
but rather for organic solvents or the like. I think fo the most part if its soluble in alcohol its soluble in acetone, and the same applies to
insolubility.
