The life span of a Daniel cell may increased by:
The life span of a Daniel cell may increased by:
- A. large Cu electrode
- B. lowering of CuSO \( _{4} \) concentration
- C. lowering of ZnSO \( _{4} \) concentration
- D. large zinc electrode
Step-by-step solution
The Daniel cell is a galvanic cell with a zinc anode and a copper cathode. The life span is limited by the consumption of the zinc anode as it oxidizes to Zn²⁺. Increasing the size of the zinc electrode provides more zinc for the reaction, thereby extending the cell's life.
