Question

what is the colour of ferrous sulphate crystals how does this colour change after heating this is question numbera then question number b name the products formed on strongly heating ferrous sulphate crystals what type of chemical reaction occurs in this change

Answer 1

The ferrous sulphate crystals are light green in colour.
On heating, the colour changes from light green to white. On further heating, the white substance changes to dark brown solid.
Decompositiom Reaction

Answer 2

Answer:

Green crystals of ferrous sulphate are their colour

Explanation:

Green crystals of ferrous sulphate are their colour.

Water molecules are present in ferrous sulphate crystals (FeSO4. 7H2O). Anhydrous ferrous sulphate (FeSO4) is produced when ferrous sulphate crystals are heated and lose their water content. As a result, they turn from bright green to white.

Anhydrous ferrous sulphate breaks down into ferric oxide (Fe2O3), sulphur dioxide (SO2), and sulphur trioxide with additional heating (SO3). Thus, the gas released has a sulfuric burning smell.

FeSO4 is the only reactant, and during this reaction, it breaks down into three distinct products. Decomposition is the reaction's primary kind.

2FeSO4(s)→Fe2O3(s)+SO2(g)+SO3(g)

ferrous ferric oxide, ahydrous

White sulphate (brown)
