Question

Is this a hydrate or no?

1.A chemist is attempting to determine if a white solid is a true hydrate heats the sample and observes water droplets on the side of the test tube. The residue obtained is dark red and dissolves in water, producing a solution that is dark red. Is this a true hydrate? Provide full reasoning.
2. A chemist is attempting to determine if a different white solid is a true hydrate heats the sample and observes water droplets on the side of the test tube. The residue obtained is white and dissolves in water, producing a solution that is colorless. Is this a true hydrate? Provide full reasoning.

1. Yes, the white solid is a true hydrate. When the sample is heated, water droplets are observed on the side of the test tube which is an indication of the presence of water in the sample. The residue obtained is dark red which indicates that the sample is likely a transition metal compound. When it dissolves in water, it produces a dark red solution which further confirms that it is a true hydrate. The dark red color of the solution is due to the presence of the transition metal ions in the compound.

2. No, the white solid is not a true hydrate. When the sample is heated, water droplets are observed on the side of the test tube which indicates the presence of water in the sample. However, the residue obtained is white which suggests that the sample is not a transition metal compound. When it dissolves in water, it produces a colorless solution which further confirms that it is not a true hydrate. The colorless solution indicates that there are no transition metal ions present in the sample. Therefore, it is not a true hydrate.
