Most likely, mercury was used as a colorant, specifically red. This list shows mercury providing a red color in flame tests, and the same would presumably be seen in fireworks. Several other, less dangerous elements also give red or reddish colors. This site identifies lithium as providing the color in red fireworks, and also mentions lithium carbonate ...

In "Fireworks, the Art, Science, and Technique", Takeo Shimizu gives a very good explanation of color production. For blue, the color-producing firework chemical is thought to be copper monochloride. If there is no free chlorine in the flame, there can be no blue color.The discovery of colors produced by chlorine along with other elements belongs to Chertier,...

As iron is one of few metals not forming amalgams, Almost all metals can form amalgams with mercury, the notable exceptions being iron, platinum, tungsten, and tantalum. ..it should preferably contaminate the mercury surface. I would try, perhaps repeated, dropping mercury, e.g via punched filtration paper to sulphuric acid bath. It can be combined ...

Don't use a mixture, just use pure Hg. Chill to 4.2 K, conveniently reached with liquid He, and all magnetic fields are excluded. Levitate on a magnet, sans yogi. Mercury in a static magnetic field, with direct current, forms a simple homopolar electric motor, creating a vortex. A safer way (sans neurotoxic Hg) to demonstrate a homopolar motor requires just ...

To spare everyone watching the movie (and giving revenue to someone showing fake chemistry), here is a summary: A container labeled "27/27 | 99%999 | 1/Kg | 001200300 | RED MERCURY | W. GERMANY | WARNING - DANGEROUS | WARNING - OPEN IN LAP" containing a red liquid is first inverted, then a metal wire (safety pin) is placed on it. The metal wire ignites. ...

There are several redox reactions can be taken place when you add household beach on elemental mercury metal. However, this question is more like a homework question. Thus, I give you insight to the answer and you may read a bit and find out what's happening. This reaction is studies and results have been published (Reference 1), the abstract of which states ...

Non-amalgamation of mercury with iron means that the iron is not dissolved, and therefore floats on the surface as a dross. However, non-amalgamation does not mean total insolubility. If a few ppm of iron needs to be removed, washing with a dilute solution of HNO3 might be best, with much agitation. There will be some dissolution of mercury to Hg++. That's ...
