4.31C Oxidation of ethanol question 1
[Maximum number: 1]
Some cars in Brazil use ethanol, C2H5OH, as a fuel instead of petrol.
The ethanol is made by the fermentation of glucose which is obtained from sugar cane.
The sugar is extracted from the sugar cane and then dissolved in water to make a sugar solution.
When ethanol is heated with acidified potassium dichromate(VI), it is oxidised to ethanoic acid.
State the colour change that occurs in the potassium dichromate(VI) during this reaction.
