CLICK HERE TO SEE QUESTION 4 An electrоchemicаl cell is set up under stаndаrd cоnditiоns using a cobalt (negative) electrode and an inert platinum (positive) electrode, as shown below. The cobalt electrode is immersed into a solution of pink cobalt(II) chloride, CoCl2(aq), and the platinum electrode is immersed into a solution of a mixture of tin(II) chloride, SnCl2(aq), and tin(IV) chloride, SnCl4(aq). A very high resistance voltmeter V and low resistance bulb are connected in parallel together with a switch S, as shown. 4.1. What type of electrochemical cell is shown in the diagram above? (1) 4.2. Are the reactions in these types of cells endothermic or exothermic, give a reason for your answer. (2) 4.3. Identify the cathode. (2) 4.4. Write down the reduction half-reaction. (2) 4.5. Calculate the initial reading on the voltmeter under standard conditions. (4) 4.6. Write down the cell notation for this cell, including phases. (5) Switch S is now closed for a certain period of time, causing the bulb to draw a current. The average current drawn is 4,43 A, resulting in the change in mass of the cobalt electrode to be 8,85 g. 4.7. Write down the oxidation half-reaction that occurs. (2) 4.8. How would the mass of the cobalt electrode change? State only INCREASE or DECREASE. (1) 4.9. Calculate the change in moles of the cobalt electrode. (2) 4.10. The change in mass of the cobalt electrode is due to the transfer of 28 950 C of charge through the circuit. Determine how long it would take for this change in mass to occur. (2) 4.11. Suggest ONE change that could be made to the construction of this cell that would increase the maximum current that it can provide. (1) [24]
