Gold Chloride Trihydrate

Gold chloride trihydrate is a chemical compound with the molecular formula AuCl3•3H2O. It is also known as trichloroauric acid trihydrate or simply gold(III) chloride trihydrate. The compound consists of one gold atom and three chlorine atoms, each of which is attached to the gold atom through a covalent bond.

The addition of three water molecules per molecule of gold chloride forms the trihydrate form of the compound. This means that for every molecule of gold chloride, there are three molecules of water associated with it. The presence of water molecules in the crystal structure of the compound affects its physical properties, such as its melting and boiling points, solubility, and reactivity.

Gold chloride trihydrate is a yellow-orange crystalline solid that is highly soluble in water and ethanol. It can be used in various applications, such as in the synthesis of gold nanoparticles, as a catalyst in organic reactions, and in electroplating processes.

It is important to note that gold chloride trihydrate is a highly toxic compound and should be handled with caution. It can cause skin and eye irritation, respiratory problems, and even death if ingested or inhaled in large amounts. Protective equipment, such as gloves, goggles, and respirators, should be worn when handling this compound.
