Periodic acid, ionization equilibria

Pauli exciusion principle. No two electrons in an atom can have the same four quantum numbers. (7.8) percent composition. The percent by mass of each element in a compound. (3.5) percent ionization. The ratio of ionized acid concentration at equilibrium to the initial concentration of acid. (16.5) percent by mass. The ratio of the mass of a solute to the mass of the solution, multiplied by 100%. (13.3) percent yield. The ratio of the actual yield of a reaction to the theoretical yield, multiplied by 100%. (3.10) period. A horizontal row of the periodic table. (2.4)... 

The new ligand (6) also bears a 3— charge when it is fully ionized, but a recent kinetic study of its formation reactions in fact dealt with 2-h cations, specifically of Ca, Mg, Mn, and Cd. This primarily thermodynamic study reveals some tantalizing hints on kinetic behavior, for example the period of about 5 hours mentioned for the Mn " plus (6) system to come to equilibrium/ Lanthanide(III) cations react with (7) about a hundred times faster, but with (8) about ten times slower, than with the much-studied >NCH2C0 ligand (3)/ Rate constants for dissociation of lanthanide(III) complexes of (7) and (8) are, in the present context, rather rapid—of the order of 10 to 10 s in neutral solution, with the usual acid-catalyzed pathway/ ...
