... yield. It runs from 0% (all reactants) to 100% (all products). This is simply more convenient than Q, which runs from 0 to infinity. The way I look at it is this for a weak acid: %ionization = [A−]eq/[HA]o x 100% That is, the “final” concentration of A− at equilibrium divided by the “initial” concen ...

Answer on Question #44399 – Chemistry – Other HC2O4 − + HOH
... Answer According to the Brønsted–Lowry theory, an acid is a species able to lose, or "donate" a proton (H+) while a base is a species with the ability to gain, or "accept," a proton. The hydrogen oxalate ion can gain a proton acting as a base towards water, while the latter donates proton acting as ...

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.
