What is Arsenic Trichloride Like?
Arsenic trichloride is usually a clear liquid, but sometimes it can look a bit yellowish. It gets very cold before it freezes, turning solid at about -16°C (that's 3°F!). It boils and turns into a gas at 130.2°C (266.4°F).
This compound reacts strongly with water. When it mixes with water, it creates two new substances: arsenous acid and hydrochloric acid. You might also notice it making misty fumes if it's in damp air. It's very important to know that arsenic trichloride is extremely poisonous and must be handled with great care.
How is it Made?
Scientists can make arsenic trichloride in a few ways. One way is by mixing arsenic metal directly with chlorine gas. Another method involves reacting arsenic trioxide (which is another arsenic compound) with either hydrochloric acid or a chemical called sulfur monochloride.
What is it Used For?
Arsenic trichloride is mainly used to create other types of arsenic compounds. It's also important in making special compounds that contain both arsenic and carbon, which are used in organic chemistry.
