A portion of solid X was placed into three separate solutions in order to estimate where X sits in the reactivity series. $X(s) + \text{FeSO}_4(aq) \rightarrow$ no reaction $X(s) + 2\text{HCl}(aq) \rightarrow X\text{Cl}_2(aq) + \text{H}_2(g)$ $X(s) + \text{Zn(NO}_3)_2(aq) \rightarrow$ no reaction Which other solution would react with solid X?
- A$\text{CaSO}_4(aq)$
- B$\text{CuSO}_4(aq)$
- C$\text{MgSO}_4(aq)$
- D$\text{Na}_2\text{SO}_4(aq)$
