Concentration of NaOH solution produced by diaphragm electrolytic cell is about _______________ percent?
Correct answer: A. 10
- A. 10
- B. 25
- C. 50
- D. 98
Explanation
The diaphragm cell produces relatively dilute caustic soda, typically about 10 to 12% NaOH, because the catholyte is diluted by water. Higher concentrations such as 50% require subsequent evaporation.
