Question

what is decomposition reaction name the product when ferrous sulphate crystals are heated​

Answer 1

Answer:

On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).

Answer 2

Answer:

Explanation:

When a single reactant break down to form simpler products, it is known as  decomposition reaction.

There are three types of decomposition reactions:

• Thermal decomposition - using heat
• Photo decomposition - using light or sunlight
• Electrolytic decomposition - using electricity

When ferrous sulphate crystals are heated is decomposes to form Ferric oxide which is colourless.

$FeSO_{4}$ ⇒ $Fe_{2} O_{3} + SO_{2}+SO_{3}$ (When heat is supplied).
