Figure Q3: The Galvanic Cell
The mass of the electrode on the left was found to increase after the experiment end. The half
reaction was shown as below:
Sn2* (aq) + 2e - Sn(s) E° = -0.14 V
X* + 3e - X(s) E° = Y
Based on Figure Q3:
(a) Label the cathode and explain your answer.
(b) State the direction of electron flow for this galvanic cell.
(c) Calculate Y, if the E'cell is +0.81V.
