Abstract
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, and [TMPO] is the concentration of TMPO in the sample in mole·liter. (II) TheP chemical shifts of the multiple samples are measured byP NMR and compared to standardized samples to determine the acid strength of the medium.
