Making Rotten Eggs Essence. Liquid Hydrogen Sulfide.

In this fascinating video, we delve into the world of hydrogen sulfide - a colorless, toxic gas with a distinct and unpleasant odor, often described as smelling like rotten eggs or fart. We start by synthesizing liquid hydrogen sulfide in the lab, using the hydrolysis of aluminum sulfide. You'll witness the chemical reaction taking place, producing high-purity hydrogen sulfide.

As we explore the properties of liquid hydrogen sulfide, you'll discover that it is highly flammable and reacts explosively with some substances, such as chromyl chloride and dinitrogen tetroxide and you'll see sulfur forming in various reactions.

We'll also examine the effects of bubbling hydrogen sulfide through concentrated nitric acid, resulting in the formation of large amounts of nitrogen dioxide, and how hydrogen sulfide reacts with iodine monochloride, producing elemental iodine. You'll also see some stunning reactions with other substances, such as lead dioxide, sodium and potassium peroxides, selenous acid, etc.
