6. What Are The Physical Properties Of AuCl3?

Gold(III) chloride (AuCl3) is a yellow to reddish-brown crystalline solid. It has a melting point of 254 °C and a boiling point of 300 °C. AuCl3 is slightly soluble in water, but more soluble in organic solvents such as ethanol and acetone. It is also hygroscopic, meaning that it readily absorbs water from the air.

AuCl3 is a strong oxidizing agent and can react violently with reducing agents. It is toxic if ingested or inhaled and can cause skin irritation upon contact. Therefore, appropriate safety measures should be taken when handling this compound.
