(a(i))[1]
Name the piece of apparatus labelled C.
(a(ii))[1]
What function does apparatus C serve?
(b)[4]
After the mixture in the flask has been heated for some time, all the ethanol will be oxidised to ethanoic acid. Draw a diagram to show how the apparatus can be changed so that the ethanoic acid may be distilled from the mixture left in the flask. Add any extra apparatus needed for the distillation to work.
(c)[2]
Ethanoic acid has a boiling point of $118\degree\text{C}$. Suggest which compound in the final reaction mixture will distil over first, and state the temperature at which this happens.
(d)[1]
What observation is made when a small volume of ethanoic acid is added to a test-tube of aqueous sodium carbonate?
