2. A colorless crystalline compound when dissolved in water formed a colorless solution . This compound was heated in a clean, dry test tube. This heating produced several drop- lets of water on the upper region of the test tube. The residue was dissolved in water and formed a yellow-brown solution. a. Determine if this colorless crystalline compound is a true hydrate or not. b. Give reasons.
