Question

What is observed when ferrous sulphate is heated continuously in a test tube. Write the equation for it and name the type of reaction in this case?

Answer 1

When ferrous sulphate is heated a mixture of SO2 and SO3 gas is liberated. Ferrous sulphate crystals loose their water of crystallition. The chemical reaction is displacement reactionEqn is as follows:-

Fe2SO4.7H2O= Fe2O3 + SO2 + SO3+ H2O

Answer 2

Answer:

we both are mohit hehe

Explanation:

Following two observations are observed when crystals of ferrous sulphate are heated: (1) Change in state and color takes place. (2) A gas is evolved during this process. Since, the compound (ferrous sulphate) decomposes into two or more substances therefore, it is a decomposition reaction
