10PRACTICE PROBLEM
A voltaic cell with an overall cell reaction Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s) is built similar to the diagram shown below. The electrodes of the half-cells are made up of a strip of Zn placed in a Zn(NO3)2 solution and a strip of Co placed in a CoCl2 solution. In what direction do the cation and anion flow through the solution?
