Activity 1.5 Ncert Science class 10

Procedure: Activity 1.5  asks us to heat ferrous sulphate crystals (aka Green vitriol) in a test tube and see what happens.

Observation: The Green colour of ferrous sulphate changes to brown and peculiar sulphur smell comes out from the test tube.

Ferrous sulphate decomposes into ferric oxide

Inference: Heating ferrous sulphate on test tube leads to decomposition of ferrous sulphate into a ferric oxide which is brown. It also liberates sulphur dioxide gas which has a foul smell.
