The "Pharaoh's snake" or "Pharaoh's serpent" is the ...
A column of porous black graphite formed during the experiment. Carbon snake experiment. The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1]
In Carbon snake demo, paranitroaniline can be used instead of sugar, if the experiment is allowed to proceed under an obligatory fumehood. [11] With this method the reaction phase prior to the black snake's appearance is longer, but once complete, the black snake itself rises from the container very rapidly. [12]
Because of this, a heptazine-based structure similar to Liebig's melon, a compound initially prepared around the same time that the pharoah's snake reaction was discovered, was not ruled out by the authors as a partial component of the solid material. [10] The generalized reaction is as follows: 2 Hg(SCN) 2 → 2 β−HgS + CS 2 + C 3 N 4
