In Diaphragm Cell, level of brine in the anode compartment is kept slightly higher which prevents:
Correct answer: A. Hydroxide ions to reach the anode
- A. Hydroxide ions to reach the anode
- B. Chlorine gas to mix
- C. Cathode to decay
- D. All of the above
Explanation
Option A is correct as that makes sure that the flow of liquid is always from "left to right" - preventing any of the sodium hydroxide solutions formed from finding its way back to where chlorine is being produced. If Hydroxide ions reach anode, they will react explosively with Chloride ions.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
