For preparation of which of the following compounds is the chlor -alkali process used?
NaOH + Cl2
The correct answer is option 1 I.e. NaOh + Cl2 .
The Chlor-alkali process is used for the preparation of:
Sodium hydroxide (NaOH) and Chlorine gas (Cl₂)
(also produces Hydrogen gas (H₂) as a byproduct)
Reaction:
2NaCl (aq) + 2H₂O (l) → 2NaOH (aq) + Cl₂ (g) + H₂ (g)
So yes, NaOH + Cl₂ are the main products of the Chlor-alkali process.
