Cr(Oh)6 3- Colour - Showing amphoteric behaviour, since the hydroxide ppt.. Chromium trioxide (also known as chromium(vi) oxide or chromic anhydride) is an inorganic compound with the formula cro3. Showing amphoteric behaviour, since the hydroxide ppt. Chromium has different oxidation states +2, +3 , +6. Or more simply cr(oh)3(s) + 3ohñ(aq) ==> cr(oh)63ñ(aq). Learn vocabulary, terms and more with flashcards, games and other study tools.
The oxygens which were originally attached to the chromium are still attached in the neutral complex. And the pale green iron(ii) ion changes on oxidation to the orange iron(iii) ion, so without the indicator i'm not sure exactly how the colour change you would. But the process doesn't stop there. Cr(oh)3 is amphoteric, so it can react with acids to form cr(h2o)6(3+) again or with more base to form the cr(oh)6(3 it changes color between green/blue and purple quite for many cr(iii) compounds. Chromium(cr) is a transition element(a 3d metal).

An excess of naoh causes the green precipitate to dissolve and form a green solution of: Cr(oh)3 is amphoteric, so it can react with acids to form cr(h2o)6(3+) again or with more base to form the cr(oh)6(3 it changes color between green/blue and purple quite for many cr(iii) compounds. Although pure cr(h2o)6cl3 is purple and our solution was dark green which is probably. Chromium has different oxidation states +2, +3 , +6. But the process doesn't stop there.
