Propanol is converted into another organic compound in a continuous reactor by heating it with acidified potassium dichromate(VI). The acidified potassium dichromate(VI) is removed from each aqueous sample before testing.
A technician tests separate portions of samples taken from two points in the reactor.
| Sampling point | Colour with universal indicator | Result when warmed with fresh acidified potassium dichromate(VI) |
|---|---|---|
| Halfway through the reactor | Orange | Changes from orange to green |
| Reactor outlet | Red | Remains orange |
Name the type of reaction that happens to propanol in the reactor.
Describe what the test results show about the conversion of propanol at each sampling point.
