Relation of Pzc To Isoelectric Point
The pzc is the same as the isoelectric point (iep) if there is no adsorption of other ions than the potential determining H+/OH- at the surface. This is often the case for pure ("pristine surface") oxides in water. In the presence of specific adsorption, pzc and isoelectric point generally have different values.

“The instincts of the ant are very unimportant, considered as the ant’s; but the moment a ray of relation is seen to extend from it to man, and the little drudge is seen to be a monitor, a little body with a mighty heart, then all its habits, even that said to be recently observed, that it never sleeps, become sublime.”
—Ralph Waldo Emerson (1803–1882)
“Constancy in love is of two sorts: One is the effect of new excellencies that are always presenting themselves afresh, and attract our affections continually; the other is only from a point of honor, and a taking of pride not to change.”
—François, Duc De La Rochefoucauld (1613–1680)
