WebThe chromium (V) acid promotes a two-electron oxidation of an alcohol and becomes Cr (III). Any residues of toxic Cr (V) and Cr (VI) compounds can be destroyed by the addition of an excess of 2-propanol once the intended reaction is complete. The formation of Cr (III) is indicated by a color change to green. WebThe Chromic Acid Test Shows positive test for: 1oand 2oalcohols and aldehydes Reactions: aldehydes and primary alcohols are oxidized to carboxylic acids while the Cr+6ion in the chromic acid is reduced to Cr+3. secondary alcohols are oxidized to ketones while the Cr+6ion in the chromic acid is reduced to Cr+3. How to perform the test:
http://home.miracosta.edu/dlr/211exp6.htm WebAniline is a weak base. Aromatic amines such as aniline are, in general, much weaker bases than aliphatic amines because of the electron-withdrawing effect of the phenyl group. Aniline reacts with strong acids to form anilinium (or phenylammonium) ion (C6H5-NH3+). Although aniline is weakly basic, it precipitates zinc, aluminum, and ferric ...
