What Is Hydrogen Telluride Like?
Hydrogen telluride is a gas that has no color. It can be quite dangerous if you breathe it in. It also has a very strong, unpleasant smell, like rotten garlic.
How It Behaves
This gas is not very stable. It breaks down easily into hydrogen gas and tellurium. It can also catch fire in the air. When it burns, it creates tellurium dioxide and water. Hydrogen telluride is an acid, almost as strong as phosphoric acid. It can react with certain metals and metal oxides. When it does, it forms compounds called tellurides.
How Is Hydrogen Telluride Made?
Scientists can make hydrogen telluride in a lab. They do this by adding a strong acid to a compound that contains telluride. An example of such a compound is sodium telluride.
Why Is It Not Used Much?
Hydrogen telluride does not have many common uses. This is because it is not very stable and can be harmful.
