I would be wary of posting entire pages of text books. I assume it is covered under copyright laws? If so, you may wish to consider removing them from your posts.

Thank you!

logP and logS ?

Are you referring to factors relating to lipid solubility?

Here is page 620 from Aulton that gives a relationship betwwen P and S.

There is more detail in the section on this page 328ff.

Thank you for your time. I need to understand the solubility in water. I saw that the logP is 2.03 and thus my molecule is not soluble in water. However the solubility graph on chemicalize tells the opposite.

A brief look suggests that the solubility isn’t actually that high at all, about 0.55 g/L, but this would be pH dependant and I’m not sure if my value was of the neutral form or not. 

I also saw that value of solubility. The graph on chemicalize remains a mistery to me.

Thank you for your answer!

Secobarbital has a logP value = 2.03 an so is not soluble in water. However, looking at the logS/pH graph on chemicalize, it is marked "Solubility category: High". 
Thank you in advance.
