Electrolysis is carried out in three cells(A) 1.0 M CuSO4 Pt electrode...
Explanation:
Cell (A) 1.0 M CuSO4 Pt electrode:
- In this cell, copper ions are reduced at the cathode to form solid copper.
- The reduction of copper ions at the cathode leads to a decrease in the concentration of copper ions in the solution.
- As a result, the pH of the solution will decrease due to the decrease in the concentration of Cu2+ ions.
Cell (B) 1.0 M CuSO4 copper electrodes:
- In this cell, copper ions are reduced at the copper cathode to form solid copper.
- The reduction of copper ions at the cathode also leads to a decrease in the concentration of copper ions in the solution.
- However, since the copper electrodes are also being consumed in the process, the concentration of Cu2+ ions in the solution remains relatively constant.
- Therefore, the pH of the solution will remain constant in this cell.
Cell (C) 1.0 M KCl Pt electrodes:
- In this cell, water is electrolyzed to form oxygen gas and hydrogen ions at the anode.
- The formation of hydrogen ions at the anode leads to an increase in the concentration of H+ ions in the solution.
- As a result, the pH of the solution will increase due to the increase in the concentration of H+ ions.
Therefore, the correct set of pH changes in the three cells would be a decrease in cell (A), a constant pH in cell (B), and an increase in pH in cell (C). Hence, option 'c' is the correct answer.
Cell (A) 1.0 M CuSO4 Pt electrode:
- In this cell, copper ions are reduced at the cathode to form solid copper.
- The reduction of copper ions at the cathode leads to a decrease in the concentration of copper ions in the solution.
- As a result, the pH of the solution will decrease due to the decrease in the concentration of Cu2+ ions.
Cell (B) 1.0 M CuSO4 copper electrodes:
- In this cell, copper ions are reduced at the copper cathode to form solid copper.
- The reduction of copper ions at the cathode also leads to a decrease in the concentration of copper ions in the solution.
- However, since the copper electrodes are also being consumed in the process, the concentration of Cu2+ ions in the solution remains relatively constant.
- Therefore, the pH of the solution will remain constant in this cell.
Cell (C) 1.0 M KCl Pt electrodes:
- In this cell, water is electrolyzed to form oxygen gas and hydrogen ions at the anode.
- The formation of hydrogen ions at the anode leads to an increase in the concentration of H+ ions in the solution.
- As a result, the pH of the solution will increase due to the increase in the concentration of H+ ions.
Therefore, the correct set of pH changes in the three cells would be a decrease in cell (A), a constant pH in cell (B), and an increase in pH in cell (C). Hence, option 'c' is the correct answer.
