For which use is chlorine gas most suitably used?
Answer and explanation
Correct answer: For killing germs in water purification
Chlorine is a strong disinfectant because it reacts with water to form substances such as hypochlorous acid, which can destroy many microorganisms. Controlled chlorination is therefore used to make drinking water safer. Antacids reduce stomach acidity, carbon dioxide makes cakes rise, and chlorine is not normally selected simply to acidify soil. Hence option A correctly matches the property with its use.
