Other things being equal, the life of a daniell cell may increased by-...
Explanation:
A Daniell cell is an electrochemical cell consisting of two half-cells, one containing a copper electrode and a copper(II) sulfate solution and the other containing a zinc electrode and a zinc sulfate solution. The two half-cells are connected by a salt bridge.
The life of a Daniell cell can be increased by using a large zinc electrode. The reason for this is that the rate of consumption of zinc in the cell is directly proportional to the surface area of the zinc electrode. Therefore, a larger zinc electrode will last longer than a smaller one because it has a greater surface area and can provide more electrons.
Other options and their explanations:
1. Keeping low temperature: This will decrease the rate of the reaction, but it will not increase the life of the cell.
2. Using a large copper electrode: This will not increase the life of the cell because the rate of consumption of copper is not a limiting factor in the cell.
3. Decreasing the concentration of copper ions: This will decrease the rate of the reaction, but it will not increase the life of the cell.
Therefore, the correct answer is (4) using a large zinc electrode.
