Question 8
F

A student heats blue hydrated copper(II) sulfate crystals in a boiling tube until the solid has turned white. The student then lets the tube cool and adds a few drops of water to the white solid.

hydrated copper(II) sulfate ⇌ \rightleftharpoons\,⇌ anhydrous copper(II) sulfate + water

Describe what the student would observe during this experiment and explain what the observations show about the reaction.
