Which base is obtained in the solution during the chlor-alkali process?

Answer and explanation

Correct answer: Sodium hydroxide

In the chlor-alkali process, concentrated brine, NaCl(aq), is electrolysed. The overall reaction is 2NaCl + 2H₂O → 2NaOH + Cl₂ + H₂. Chlorine and hydrogen are released as gases, while sodium hydroxide is obtained in the solution. Therefore option A is correct. The other hydroxides are not formed from sodium chloride electrolysis in this process.
