Ph level of aniline
WebbThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … Webbaniline oligomers with the iron oxide surface. Phenyl capped aniline dimer with two oxidation states [fully reduced (DPPD) and fully oxidized (B2Q1)] and phenyl-capped aniline tetramer (PCAT) with three oxidation states [fully reduced (B5), half-oxidized (B4Q1), fully oxidized (B3Q2)] were chosen for investigation.
