The protonation constants of a set of solvatochromic pyridinium-N-phenolate betaine dyes I–XI (D±) were determined in methanol, water, and the ternary solvent mixture benzene – ethanol – water (with mass ratio 47:47:6) using the vis spectroscopic method. Both, medium effects on transferring from wat...
