A Voltaic Cell (also known as a Galvanic Cell) is an electrochemical cell that uses spontaneous redox reactions to generate electricity such as in Figure Q3. Voltmeter Switch Wire Salt Bridge A Sn 1.0 M Sn(NO,); 1.0 M X(NO,), 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) Eº = -0.14 V X3+ + 3e → X(s) E° = Y Based on Figure Q3: 9 State the direction of electron flow for this galvanic cell. Calculate Y, if the E'cell is +0.81V. C Identify A.

PART II) -Q1 for the following Redox reaction: Co, + 2H > Co* + Haa) (aq) 1) Draw a detailed diagram of the cell: anode, cathode, salt bridge and the direction flow of the electrons.{Remember Co is one of the two electrodes & S.H.E. is the other electrode}
