In a weak acid such as ethanoic acid, only some of the acid molecules release their hydrogen ions when they are in water, so the reactions of weak acids are not as vigorous as the reactions of strong acids. In a weak base such as sodium hydrogen carbonate, NaHCO3 (baking soda), only some of the base ...

Entering and leaving group effects in Oh ligand substitutions

Ligands trans-to each other compete for electron density because both M-L bonds use the same metal orbitals, e.g. dz2 or pz See p. 831 in Ch.22, Box 22.8: Very strong -donors (e.g. H– and alkyl– ligands) compete for orbital overlap at the metal with the leaving group: this weakens the M-L bond in t ...

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.
