Specific gravity of electrolyte in Edison cell is_____________?
Correct answer: D. 1.21
- A. 0.8
- B. 0.95
- C. 1.1
- D. 1.21
Explanation
The Edison, or nickel-iron, cell uses potassium hydroxide electrolyte with a specific gravity commonly taken as about 1.21. Values near 0.8 or 0.95 are too low for this alkaline electrolyte.
