Diaphragm cell and electrolysis in membrane cell

Question 1

what is the function of the diaphragm to produce sodium hydroxide, chlorine and hydrogen

Answer 1

Diaphragm cell stops the mixing of chlorine, sodium hydroxide and oxygen because together it can be explosive

negative chloride ions are attracted to the positive anode

positive hydrogen ions are attracted to the negative cathode

Question 2

What is the function of the membrane in the cell

Answer 2

membrane keeps chlorine gas separate from hydrogen gas

chlorine will not be able to react with hydrogen

membrane allows Na+ to pass through

sodium hydroxide solution is not contaminated with chloride ions
