Question

A student has three samples of Ferrous sulphate crystals in separate test tube X, Y and Z. The colour of Ferrous sulphate in X is green, in Y is white and in Z is green. Which test tube requires heating to remove water of crystallization? (Please answer fast I’ll mark you the brainiest)

Answer 1

Answer:

Ferrous sulphate crystals contain water molecules (FeSO4. 7H2O). On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white.
