FAQ

What are the physical and chemical properties of Gold(III) chloride trihydrate (CAS: 16961-25-4)?

Gold(III) chloride trihydrate is a crystalline solid with a molecular formula of AuCl3·3H2O. Its molecular weight is approximately 414.4 g/mol. It is sparingly soluble in water and ethanol. Chemically, it is highly reactive with reducing agents and can undergo hydrolysis under basic conditions. It has an orange-yellow color and is commonly used in analytical chemistry and as a precursor in gold chemistry.

How is Gold(III) chloride trihydrate (CAS: 16961-25-4) typically synthesized?

Gold(III) chloride trihydrate can be synthesized by treating gold(III) oxide with hydrochloric acid followed by crystallization from water. The reaction is typically carried out under controlled conditions to achieve high selectivity and yield. This process requires careful handling to prevent the formation of other gold compounds.

What industries use Gold(III) chloride trihydrate (CAS: 16961-25-4)?

Gold(III) chloride trihydrate is used in various industries, including pharmaceuticals, where it is used in the synthesis of gold-containing drugs. It is also used in polymer research for the synthesis of gold-containing polymers, in sensors for its unique optical properties, and in semiconductor manufacturing for its use as a precursor in the deposition of gold films.

What precautions should be taken when handling Gold(III) chloride trihydrate (CAS: 16961-25-4)?

When handling Gold(III) chloride trihydrate, it is important to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. Work should be conducted in a fume hood due to its reactivity. Spills should be handled with care, and the area should be cleaned thoroughly. Safety data sheets (SDS) should be consulted for detailed information on handling and emergency procedures.
