Which of the following is wrong statement about Nelson Cell?
Correct answer: C. The level of brine in the cathodic compartment is higher than anodic compartment
- A. It is also called diaphragm cell
- B. Used for commercial preparation of NaOH
- C. The level of brine in the cathodic compartment is higher than anodic compartment
- D. Constant level device is used
Explanation
Nelson Cell, also known as the diaphragm cell, is an electrolytic cell used for the commercial preparation of sodium hydroxide (NaOH) and chlorine (Cl2) from brine (NaCl solution). In a Nelson Cell, a diaphragm separates the cathodic and anodic compartments. The brine flows into the anodic compartment where chlorine gas is produced, and sodium ions migrate through the diaphragm to the cathodic compartment, where sodium hydroxide solution is formed.
