Ethanol can be oxidised by being
Burnt in air(complete combustion)
Ethanol can be oxidised by
Having a reaction with oxygen in the air to form ethanoic acid(microbial oxidation)
Ethanol can be oxidised by
Heating with potassium dichromate in dilute sulphuric acid to form ethanoic acid.
Ethanol can be made by
Reacting ethene with steam in the presence of phosphoric acid catalyst at 300 degrees and a pressure of 60-70 atm
Ethanol can be manufactured by
The fermentation of glucose, in the abscess of oxygen, anaerobically at 30 degrees and at normal pressure, using the enzymes in yeast
Carboxylate acids have the functional group
O
