A student wants to do electroplating on a katana made of gold, however, he realized that the concentration of the gold ions present in the solution is unknown,making the electroplating process difficult to plan. He then decided to use a galvanic cell to obtain the gold ion concentration. He used the half-cell reactions below. Write the cell notation for this cell.
