Exam points
- oxidise methanoic acid to CO2 and H2O with Tollens’, Fehling’s, acidified MnO4− or acidified Cr2O7²−
- use warm acidified MnO4− to oxidise ethanedioic acid to carbon dioxide
- distinguish these acids from a non-reducing carboxylic acid by combining test observations rather than acidity
