N2 - The solvatochromic hydrogen bond donor (HBD) acidity parameter (αmix) of aqueous mixtures of methanol, acetonitrile, propan‐2‐ol and tetrahydrofuran were determined spectrophotometrically. The study was carried out at 25deg;C as a function of composition. The indicators used were 2,6‐diphenyl‐4‐(2,4,6‐triphenyl‐N‐pyridino)phenolate, 2,6‐dichloro‐4‐(2,4,6‐triphenyl‐N‐pyridino)phenolate and Fe(LL)2(CN)2 (LL = N‐(2‐pyridylbenzylidene)‐3,4‐dimethylaniline). The HBD acidity of the aqueous organic mixtures was related to retention in reversed‐phase liquid chromatography.
