Question

Which of the following chemical reactions represents the chlor-alkali process?

• A. NaHCO3+H+CO2+H2O+ Sodium salt of acid
• B. NaCl + H2O + CO2 + NH3 NH4Cl + NaHCO3
• C. 2NaCl (aq) + 2 H2O (1)→2 NaOH (aq) + Cl2 (g) + H2 (g)
• D. Ca(OH)2 + Cl2→ CaOCl2 + H2O

Answer 1

Answer:

C. 2NaCl (aq) + 2 H2O (1)→2 NaOH (aq) + Cl2 (g) + H2 (g)

• The chlor-alkali process involves the electrolysis of brine (NaCl solution),producing NaOH,Cl2 and H2

• Therefore, option C represents this process.
