Hydrogen tetrachloroaurate hydrate

Description:
Hydrogen tetrachloroaurate hydrate, with the CAS number 27988-77-8, is a coordination compound of gold. It is typically encountered as a yellow crystalline solid, which is soluble in water and polar organic solvents. The compound consists of a gold ion coordinated to four chloride ions and a hydrogen ion, forming a complex that is often used in various applications, including catalysis and the synthesis of gold nanoparticles. The presence of water molecules in its hydrate form contributes to its stability and solubility. In terms of reactivity, hydrogen tetrachloroaurate can undergo reduction to form elemental gold or other gold compounds, making it valuable in both chemical research and industrial processes. Its properties are influenced by the coordination environment around the gold center, which can affect its electronic characteristics and reactivity. Safety precautions should be taken when handling this compound, as it contains toxic chloride ions and can pose health risks if ingested or inhaled.
