A solution of CuCl2 is placed in each of five identical small beakers. Then pieces of the five different metals listed below are obtained and one piece of metal is placed in each beaker. In some beakers, copper metal begins to accumulate on the surface of the piece of metal placed in the beaker of CuCl2 solution, and the blue-green color of the solution gradually fades until the solution becomes colorless. Which of the five metals will cause copper metal to form? Choose all correct answers; either two or three metals should be chosen.
platinum (Pt) metal
tin (Sn) metal
lead (Pb) metal
