Q
How can reverse the processes of testing for water?
A
By changing the conditions (heat causes dehydration), and so we use a sing in the equation to show this

Q
What is the equation used to represent the reverse and processes of testing for water?
A
- Hydrated copper sulfate <–>(endothermic or exothermic) anhydrous copper sulfate + water
- Anhydrous coblat chloride + water <-> Hydrated cobalt chloride
