Comments: The influence of the solvent on the protonation of citraconic and mesaconic acid in aqueous and ethanolic solutions of H2SO4 
was investigated using spectrophotometric methods. The spectra were recorded, in the 190–300 nm region, from solutions with a constant 
concentration of the organic acid (1.0 x 10-4 mol dm-3 in the case of citraconic and 2.4 x 10–4 mol dm-3 for mesaconic acid) and increasing
 concentration of H2SO4 (from 1.0 to 17.5 mol dm-3).
