A student separately warms methanol, propanol and butanol with acidified potassium dichromate(VI). In every test, the mixture changes from orange to green and an organic product forms.
Use the colour change to explain how each alcohol has changed. Predict the observation when sodium carbonate is added to each organic product and explain why the observation is the same in every case.
