For clear/colourless solution

Vedclass · Answer

(C) The reaction $ZnSO_4 (aq) + MgCl_2 (aq) \longrightarrow$ No reaction occurs because there is no formation of a precipitate or a gas,and no change in oxidation state.Both $ZnSO_4$ and $MgCl_2$ are soluble salts,and their ions remain in the solution as $Zn^{2+}, SO_4^{2-}, Mg^{2+},$ and $Cl^-$.Since no chemical change occurs,the resulting mixture remains a clear and colourless solution.Therefore,the correct classification for this observation is $C$.
