Answer:
Anhydrous Ferrous Sulfate crystals
Explanation:
When heating is applied on hydrated crystals, it drys the crystals so that water is evapourated away while the anhydrous crystals are still in the test tube. This can be observed by the decolorisation of crystals from its color while hydrated to a white color while anhydrated.
