1. Apple smell, which is actually ethanal. Orange to green.
2. The ethanol reduces Cr-VI to Cr-III
3. All oxidising agents with oxygen to get rid of need H+ ions in order to make water.
4. (Cr2O7)2- is the oxidising agent, and CH3CHO is the initial oxidation product. Under certain conditions CH3COOH can be produced by further oxidation.
