What happens to brine when electrolysed?

When brine (a concentrated solution of salt, typically sodium chloride) is electrolyzed, it undergoes a chemical reaction that produces chlorine gas at the anode and hydrogen gas at the cathode, along with sodium hydroxide (NaOH) in the solution. The chlorine gas can be collected for various industrial uses, while the hydrogen gas may be used as a fuel or for other chemical processes. This process is commonly used in the chlor-alkali industry to produce these valuable chemicals.
