When they reach this metal, they combine with the cadmium ions forming our cadmium solid. So, in the third step, we basically want to use this cell voltage formula to find our cell voltage for the cathode. Remember? Now, we know that this guy, this value of negative zero point 76 represents the value for the anode. So we use this formula to solve for our cathode. So we know our 0.36 volts, which is told by the voltmeter.
