Abstract

See full text

A method to determine the strength of an acid in a medium is disclosed. The method includes (I) providing multiple samples comprising trimethylphosphine oxide (TMPO), the acid, and the medium, wherein the multiple samples have different [H+]/[TMPO] ratios, [H+] is the concentration of hydrons in the sample in mole·liter−1, and [TMPO] is the concentration of TMPO in the sample in mole·liter−1. (II) The 31P chemical shifts of the multiple samples are measured by 31P NMR and compared to standardized samples to determine the acid strength of the medium.
