Question

Assertion: Green vitriol is hydrated ferrous sulfate.

Reason: Chemical formula of green vitriol is ${\mathrm{FeSO}}_4.7{\mathrm{H}}_2\mathrm{O}$

• A. Both assertion and reason are correct and the reason is the correct explanation of the assertion.
• B. Both assertion and reason are correct but the reason is not the correct explanation of the assertion.
• C. The assertion is correct but the reason is incorrect

Both assertion and reason are correct and the reason is the correct explanation of the assertion.

Explanation for the assertion statement:

The common name of ferrous sulfate heptahydrate is green vitriol due to its green color.

Explanation for the reason statement;

This statement is true as-

1. Hydrated ferrous sulfate has 7 molecules of water as water of crystallization.
2. Thus the formula is ${\mathrm{FeSO}}_4.7{\mathrm{H}}_2\mathrm{O}$.

Therefore, both assertion and reason are correct and the reason is the correct explanation of the assertion.

Hence, option A is correct.
