Reactivity 3.1.9 - the pOH scale describes the concentration of a solution. ;

NOTE

this relationship is true only at 298K as the ionic product of water changes with temperature.

strong acids and bases: and can be deduced from their concentrations

as full dissociation is assumed for strong acids and bases, the ion concentrations can be calculated directly from the initial concentration. note that the and are derived from the equilibrium concentrations of and
