Write the balanced chemical equation of chlor - alkali process

Chlor-alkali process, as the name suggests, is a method that leads to synthesis of Cl₂ and NaOH,an alkali.It is brought about by electrolysis of brine i.e. aq. NaCl sol..

The  chemical equation for chlor-alkali process can be written as follows:

NaCl + H₂O→NaOH + Cl₂ + H₂

Upon balancing it by simply ensuring equal number of atoms of each element on either sides, equation obtained is :2NaCl + 2H₂O →2NaOH + Cl₂ + H₂

Hence, post balancing,balanced chemical  equation of chlor-alkali process or brine electrolysis is as given below:

2NaCl + 2H₂O →2NaOH + Cl₂ + H₂
