... The pH of a solution is calculated from its [H3O+]. NaOH is an ionic solid that is a strong base and dissociates completely to produce a high OH– concentration (low [H3O+]). Since [OH–] is high / [H3O+] is low, the pH is high. NaOH → Na+ + OH– CH3NH2 is a weak base that partially reacts / dissociate ...

Equilibrium chemistry
Equilibrium chemistry is a concerned with systems in chemical equilibrium. The unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero. This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Applications include acid-base, host-guest, metal-complex, solubility, partition, chromatography and redox equilibria.
