Calculate difference between oxidation state of chromium (Cr) in blue and green coloured chromium sp — Reaction Mechanism Chemistry Question
Question
Calculate difference between oxidation state of chromium (Cr) in blue and green coloured chromium species formed during the following given transformation.
Answer: **3** / TRANSFORMATION INVOLVES CRO4^2- + H2O2/H+ -> CRO5 (BLUE SOLUTION, OXIDATION STATE = +6). CRO5 DECOMPOSES TO CR3+(AQ.) (GREEN, OXIDATION STATE = +3). DIFFERENCE = 6 - 3 = 3.
