Appearence

Aluminum tribromide typically appears as a white to pale yellow solid. It is highly hygroscopic and can exist in different forms depending on the conditions. When pure and anhydrous, it forms colorless crystals, but it can also appear as pale yellow when it contains impurities or is exposed to moisture. In the presence of moisture, it can also appear as a liquid due to its deliquescent nature.
