A student warms propanol with acidified potassium dichromate(VI). The organic product is separated and dissolved in water. Only a small proportion of the product molecules form ions.
The student also prepares solution S. Solution S contains a strong acid at the same concentration as the solution of the organic product. The acid in solution S ionises completely.
Name the organic product formed when propanol is oxidised.
State whether the organic product is a weak acid or a strong acid.
State which solution has the lower pH.
The organic product is warmed with an alcohol and concentrated sulfuric acid.
Name this type of reaction.
