Question

Why in heating ferrous sulphate, it first releases Sulphur dioxide and then the sulphurtrioxide?

Answer 1

Ferrous sulfate changes to reddish brown due to the formation of ferric oxide. Sulfur dioxide and sulfur trioxide gases are alsoreleased in this reaction. They have a pungent and rotten smell due to the burning of sulfur. These gases are toxic

Answer 2

ANSWER:-

◆ When Ferrous Sulphate heat and form Ferrous Oxide, Sulphur Dioxide and Sulphur Trioxide.

◆ EQUATION = FeSO4 --- Fe2O3 + SO2 + SO3

◆ It is a Thermal Decomposition Reaction

◆ Thermal Decomposition Reaction = When the decomposition reaction carried by heat.
