Question

Is ferric oxide produced by the decomposition of ferrous sulphate pure. Explain and justify.

Answer 1

Answer:

yes...

when ferrous sulphate is heated is give ferric oxide,sulphur trioxide and sulphur dioxide

equation-

feSO4------->fe2O3+SO2+SO3

Answer 2

Yes, the decomposition of ferrous sulfate produces ferric oxide.

Explanation:

• The type of chemical reaction in which one reactant decomposes and yields one or more products, it is called a decomposition reaction.
• When ferrous sulfate is decomposed by heating, the following reaction occurs:

$2 \mathrm{FeSO}_{4} \stackrel{\Delta}{\rightarrow} \mathrm{Fe}_{2} \mathrm{O}_{3}+\mathrm{SO}_{2}+\mathrm{SO}_{3}$

• From the above equation, it is clear that decomposition of ferrous sulfate yields ferric oxide.

Justification:

• The reaction involved in the production of ferric chloride from ferrous sulfate is inferred as a decomposition reaction.
• It is because, it yields three products namely ferric chloride, sulfur dioxide and sulfur trioxide from ferrous sulfate.
