Which aqueous ionic solutions will react with Zn(s) at room temperature? Select all that apply.
NaCl(aq)
AuCl3(aq)
ZnCl2(aq)
FeCl3(aq)
NiCl2(aq)
AlCl3(aq)
CuCl(aq)
Solution
From the activity series of metals, it can be deduced whether solid Zinc will react (or displace) with an aqueous salt of a given metal. If the metallic zinc ranks higher in the reactivity series than a particular metal, then it can be displaced from it\'s aqueous solution or reaction will take place.
From the above list of solutions, Zinc is more reactive than Au (Gold), Fe (Iron), Ni (Nickel) and Cu (Copper). Hence, ionic solutions of AuCl3, FeCl3, NiCl2 and CuCl will react with Zinc.
