Suppose a large piece of a metallic solid, A(s), is placed in a beaker containing the metallic cation Z²⁺(aq), as depicted below. If Z is a more active metal than A, which is a possible representation of the final reaction mixture? A) I only B) II only C) III only D) I or II E) II or III

Quizplus · Accepted Answer

If Z is more active than A, then Z will displace A in the solid state and form ZS1U1P12(s). This means that the only possible product in the reaction mixture will be ZS1U1P12+S1S1P0(aq), as shown in III. Options I and II depict solid A remaining in the beaker, which is not possible if Z is more active. Therefore, the best choice is C, III only.
