Options:

Answer:

Solution:

The manufacturing of NaOH primarily occurs via the Chlor-alkali process, which involves the electrolysis of an aqueous solution of sodium chloride (brine).

The overall reaction is:

$2 N a Cl (a q) + 2 H_{2} O (l) \to 2 N a O H (a q) + C l_{2} (g) + H_{2} (g)$

During this process, chlorine gas ( $C l_{2}$ ) and hydrogen gas ( $H_{2}$ ) are produced as valuable by-products alongside sodium hydroxide (NaOH). Therefore, $C l_{2}$ is a by-product.
