Assertion : Copper sulphate solution is not stored in zinc vessel....
Assertion : Copper sulphate solution is not stored in zinc vessel.
Reason : Zinc forms complex with (\mathrm{CuSO}_4).
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
Electropositive elements like zinc precipitate copper from a solution of copper sulphate and finally forms a complex.
(\mathrm{CuSO}_4+\mathrm{Zn} \rightarrow \mathrm{Cu}+\mathrm{ZnSO}_{4(a q)} \rightarrow\left[\mathrm{Zn}\left(\mathrm{H}_2 \mathrm{O}\right)_4\right] \mathrm{SO}_4)
