Title: Potentiometric pH Measurements of Acidity Are Approximations, Some More Useful than Others.
Authors: de Levie, Robert1 rdelevie@bowdoin.edu
Source: Journal of Chemical Education. Nov2010, Vol. 87 Issue 11, p1188-1194. 7p.
Subjects: Approximation theory, Chemical engineering approximation methods, Potentiometry, Hydrogen-ion concentration measurement, Hydrogen analysis, Acidity function
Abstract: The article focuses on the approximations and significance of the potentiometric potential of hydrogen (pH) measurements of acidity. It suggests that hydrogen ion concentration's negative logarithm can be obtained through the usual potentiometric measurements. It explains that the obtained hydrogen ion concentration can be tested independently.
