Acid Base Equilibrium
... The stronger an acid is, the weaker its conjugate base will be. We can categorize acids and bases according to their behavior in water. • 1. Strong acids completely transfer their protons to water. • No undissociated molecules remain in solution. • Their conjugate bases have negligible tendencies to ...

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.
