What is the main classification of sodium hydroxide obtained in the chlor-alkali process?

Answer and explanation

Correct answer: Base

Sodium hydroxide has the formula NaOH and dissociates in water to produce sodium ions and hydroxide ions, OH⁻. A substance that supplies hydroxide ions in aqueous solution is classified as a base; NaOH is specifically a strong base because it dissociates extensively. Therefore option B is correct. It is not an acid, salt, or neutral oxide. Sodium chloride is the salt involved as the brine starting material, not the NaOH product.
