== Method ==

Weights of the three, built-in calculation methods:
  * VG (Viswanadhan, V. N.; Ghose, A. K.; Revankar, G. R.; Robins, R. K. J. Chem. Inf. Comput. Sci., 1989, 29, 163-172)
  * KLOP (Klopman, G.; Li, Ju-Yun.; Wang, S.; Dimayuga, M. J. Chem. Inf. Comput. Sci., 1994, 34, 752)
  * PHYS (PHYSPROP© database)

**Cl<sup>-</sup> concentration**

range: 0 - 0.25 M, default: 0.1 M

**Na<sup>+</sup> + K<sup>+</sup> concentration**

range: 0 - 0.25 M, default: 0.1 M


== pH ==

Calculates logarithm of the partition coefficient of the major microspecies (not neutral form) at the given pH (blank: input protonation state)

== Tautomerization ==

Consider tautomerization and resonance
