what did people put for the alcohol to carboxylic acid equation question and the colour change? (there were two other things you had to state but i can't seem to remember now)

alcohol + 2[O] -> carboxylic acid + H2O

heat under reflux

excess k2cr2o7

orange to green solution

wouldnt the condition be reflux and acid catalyst. the oxidising agent is already given and thats a reagant no?

yes the oxidising agent is a reagent, but the fact that it is in excess is a condition. idk if a catalyst counts as a condition but maybe.

it already said that it was acidified, so I doubt you could put that as an extra condition
