Anhydrous Aluminum Chloride
Anhydrous aluminum chloride, often represented as AlCl3, is a chemical compound composed of aluminum and chlorine. "Anhydrous" means it lacks water molecules in its structure. It's a white or pale yellow solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. This property makes handling it a bit tricky since it can form a solution with water vapor in the air, turning into a fuming liquid.
