Question

Write the reaction for following chemical reactions. Copper (II) Sulphate crystals are heated in a test tube.​

Answer 1

Answer:

• The colour of hydrated copper sulphate CuSO4. 5H2O is blue that turns into white, when heated at high temperature in a test tube, due to the loss of water molecules from copper sulphate.

Answer 2

Answer:

CuSO₄.5H₂O(S) ----Δ---->CuSO₄+5H₂O

The colour of hydrated copper sulphate (CuSO₄.5H₂O) is blue that turns into white anhydrous copper sulphate (CuSO₄), when heated at high temperature in a test tube, due to the loss of water molecules from copper sulphate.
