Potentiometric pH Measurements of Acidity Are Approximations, Some More Useful than Others.

APPROXIMATION theory; CHEMICAL engineering approximation methods; POTENTIOMETRY; HYDROGEN-ion concentration measurement; HYDROGEN analysis; ACIDITY function

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.
