Notes:
The protonation of acetone in water for a wide range of compositions of the binary mixture was studied by multinuclear NMR spectroscopy. Formation constants (K1 and K2) and 13C, 17O and 1H chemical shifts of the 1:1 and 1:2 complexes were evaluated. The correlation of the 1H chemical shift of uncombined water with its concentration, Δ0H2O = A + B In [H2O]eq, recently derived for the trimethyl phosphate-water system, was verified. A measure of the fraction of monomer species existing in the uncombined water at each composition was obtained. The results are discussed with respect to the structure of water.
