Estimation of the point of zero charge of simple oxides by mass titration
Open accessAbstract
A method is proposed to estimate the point of zero charge (pzc) of pure compounds which can be described accurately by the surface ionization model of amphoteric oxides. It is demonstrated that under the limiting conditions of “infinite” mass/volume ratio, the pH of the system will approach pH∞ = 12(pK1 + pK2) pzc. Experimental values of the pH of the oxides of titanium, aluminum, a silicon suspended in a closed aqueous system exhibited the existence of a constant pH at high mass fractions. This limiting pH is found to be a reasonable estimate for the point of zero charge of each oxide.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
