The "Pharaoh's snake" or "Pharaoh's serpent" is the original version of the black snake experiment. It produces a more impressive snake, but its execution depends upon mercury II thiocyanatewhich is no longer in common use due to its toxicity. Once lit, both fireworks emit smoke and spew out ash resembling a snake via an intumescent reaction. They remain on the ground and emit no sparks, flares, projectiles, or sound.
The Pharaoh's snake is a more dramatic experiment, yet it requires more safety precautions than the sugar snake due to the presence of toxic mercury vapor and other mercury compounds. It was described as "winding out from itself at the same time worm-like processes, to many times its former bulk, of a very light material of the color of graphite.
The Pharaoh's snake experiment is conducted in the same manner as the sugar snake experiment, however, the former uses mercury II thiocyanate Hg SCN 2 instead of powdered sugar with baking soda. This must be done in a fume hood because all mercury compounds are hazardous. Graphitic carbon nitridea pale yellow solid, is the main component of the ash. While carbon nitride C 3 N 4 will break down into nitrogen gas and dicyan.
When mercury II sulfide HgS reacts with oxygen O 2it will form gray mercury vapor and sulfur dioxide. If the reaction is performed inside a container, a gray film of mercury coating on its inner surface can be observed. Unlike the carbon snakewhich involves the reaction of sulfuric acid instead of sodium bicarbonatethe sugar snake grows relatively faster and to a significantly larger volume.
Solid fuel is used in this experiment. The solid fuel can be sand that is sufficiently covered in ethanol or hexamethylenetetramine. A white mixture of sucrose and sodium bicarbonate will eventually turn black and the snake will grow about 15—50 centimetres 5. Three chemical reactions occur when the snake is lit. Sodium bicarbonate breaks down into sodium carbonatewater vaporand carbon dioxide : .
Burning sucrose or ethanol reaction with oxygen in the air produces carbon dioxide gas and water vapor : . Some of the sucrose does not burn, but merely decomposes at the high temperature, giving off elemental carbon and water vapor: .
The carbon in the reaction makes the snake black. The overall process is exothermic enough that the water produced in the reactions is vaporized. This steam, in addition to the carbon dioxide product, makes the snake lightweight and airy and allows it to grow to a large size from a comparably small amount of starting material.With a performance time of 10, seconds.
