please answer soon i have my exams today...In the Chlor-Alkali process, the chlorine gas is given of at the anode and the hydrogen gas at cathode. Why is the Sodium Hydroxide formed near cathode ??

so, during Chlor alkali process the NaCl in H2O gets dissociated into Na+, Cl- and also into H+ and OH-
Technically, the Na+ and H+ being cations move towards cathode and Cl- and OH- being anions move towards anion,
H+ having higher reductional potential( can be reduced easily) moves to cathode and forms H2 gas, leaving Na
whereas Cl- gets oxidised to form Cl2 and it is formed in anode , leaving OH-
the Na+ and OH- being free in solution reacts to form NaOH, because Na being electropositive and strong cation, NaOH is formed in cathode
possibly make it as brainliest
