Aqueous solution of $$\text{CuSO}_4$$ cannot be stored in Zn container but aqueous solution of $$\text{ZnSO}_4$$ can be stored in Cu vessel. Why?

PLACEHOLDER ANSWER - the answer is an explanation. Zinc is more reactive than copper (it lies above copper in the activity series), so it displaces copper from its salt, $$\text{Zn} + \text{CuSO}_4 \rightarrow \text{ZnSO}_4 + \text{Cu}$$, and the container would corrode. Copper is less reactive than zinc and cannot displace it from $$\text{ZnSO}_4$$, so the copper vessel is unaffected.
