19 Dec 2007, 10:01 PM  | another question regarding ethanol as a solvent You can hide this advertisement by registering. I am in the middle of an open-ended investigation, where I have to use information resources to find the solubility of pure chemicals in ethanol. I understand the molecular structure of ethanol and how it is able to dissolve polar and non-polar substances, but I'm finding it really tough finding information on specific chemicals, and its solubility when added to them. Can some one please help!?thanks aimstar |

19 Dec 2007, 10:01 PM | thanks Jumbo Cactuar thanks for that, thats pretty much what I'm doin anyway, finding specific examples then discussing the applications involved. ive managed to find some pretty random examples but they will do. thanks again |

I think solubility in g/L is only given for water, though. Have a look for this book in university libraries... there is also a web edition in pdf format. |

18 Sep 2005, 9:18 PM | Solubility would be given as molal quantities. That is to say mass of solute for mass of solvent. SI Chem Data tabulates grams of solute per 100 grams of solvent (though figures only given for water). That would be because volumes of solvents (be it solid, liquid or gas) vary under many conditions.
