Solubility of Solids (solute) in Liquids (solvent):
In my specific case, the solid obtain plant tissue (trees).
Liquids or used solvents typically obtain organics and inorganics compounds. I will be waiting respectfully for your powerful expectations regarding the previous question.
Dear Baru Debtera Bejena I'm sure that many RG members would be willing and able to answer your interesting technical question. However, it would be easier to give you a qualified answer of the question was a bit more specific. For example, you could specific what kind of organic compounds you want to extract and what parts of the trees (leaves, bark etc.) you want to use.
