Question

In which we get concentrated caustic soda by membrane ,diaphrgm and membrane cell?

Answer 1

Answer:

Diaphragm cell

Similarly to the Membrane Cell, chloride ions are oxidized at the anode to produce chlorine, and at the cathode, water is split into caustic soda and hydrogen. ... A diluted caustic brine leaves the cell. The caustic soda must usually be concentrated to 50% and the salt removed.
