Copper sulfate (CuSO₄) doesn't have a specific boiling point because it decomposes before reaching a boiling point. When heated, copper sulfate pentahydrate (CuSO₄·5H₂O) loses its water molecules and transitions into anhydrous copper sulfate (CuSO₄).

Here's a breakdown:

* Copper Sulfate Pentahydrate (CuSO₄·5H₂O): This is the common form of copper sulfate, a blue crystalline solid. It decomposes at around 150°C, releasing water molecules and leaving behind anhydrous copper sulfate.

* Anhydrous Copper Sulfate (CuSO₄): This is a white powder. It decomposes at much higher temperatures, around 650°C, and it doesn't have a well-defined boiling point.

Water's Boiling Point: The boiling point of pure water is 100°C (212°F) at standard atmospheric pressure.

Important Note: The boiling point of a solution containing copper sulfate and water will be higher than 100°C due to the presence of the solute (copper sulfate). However, this boiling point will still be below the decomposition temperature of copper sulfate.
