# Is it possible to estimate a substance's water solubility from data like the substance's partition coefficient, dissociation constants, etc.?

If it is possible, how would you estimate a compound's water solubility from data like its partition coefficient, $\log P$, its dissociation constant, $pK_a$, its molar mass, etc.?

I think it can be done, but first you have to have model, so you can gather your data via vcclab.org/lab/alogps -> lots of compounds -> lots of descriptors (as you mentioned) -> output logS (solubility) -> heuristic(?) model (maybe ANN would be useful?) -> then input data -> output (predicted solubility) –  java_xof Jan 19 '13 at 22:41
Moreover similar things have been done at onschallenge.wikispaces.com/Predictive+Solubility –  java_xof Jan 19 '13 at 22:47
