Today, we will study the chemical compound TlCl3. Its common name is thallium (III) chloride. In the formula TlCl3, Tl represents the thallium atom with atomic mass 204.3833 and atomic volume 81, often represented as Tl(III) to indicate its valence +3. Cl stands for the chlorine atom, with an atomic mass of 35.45 and atomic volume 17. The TlCl3 molecule structure consists of one thallium atom and three chlorine atoms.
In terms of properties, TlCl3 is solid under standard conditions, its color ranges from white to ivory, and it is odorless. Its PH level is neutral. The chemical properties of TlCl3 are quite notable. It easily reacts with other ions to form other substances.
TlCl3 can participate in many different types of chemical reactions, from reactions with metals, acids, non-metals to salts. We will discuss examples of common reactions of TlCl3 later.
To prepare TlCl3, we can use various methods in the lab or the industry. In the lab, the common method is to treat thallium with chlorine. In the industry, this includes using chlorine to oxidize thallium, or using thallium and chlorine under high temperature conditions.
