Freeware pKa prediction software

[sfe-co2]

Hi folks,

Just wondering if there is such a program out there. Be nice to draw a compound's structure and have the program predict pKa's to different sites on the molecule.

Is this even possible in a software package I wonder.

Thanks again all.

Here is an online calculator for pKa and a few other properties:

I also highly recommend MarvinSketch which can do pKa, log P, etc.:
