What is pettenkofer test?
In the Pettenkofer test the sulfuric acid and sugar form a furfural derivative, which, under the influence of the sulfuric acid, reacts with cholic acid to produce a purplish pink color. The development of the color is a progressive reaction, the speed of which can be controlled by temperature.
