Question

Given below are two statements:
Statement I: When Chlorine is added to water, Hydrochloric acid and Hypochlorous acid are formed.
Statement II: The disinfection action of Chlorine in water is mainly due to Hypochlorous acid.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

The disinfecting power of chlorine in water comes from Hypochlorous acid (HOCl), which is formed when chlorine reacts with water. Always ensure proper dosage to maintain effective water treatment.

Answer 1

The Correct Option is A

- Statement I is correct. When chlorine is added to water, it reacts to form Hydrochloric acid (HCl) and Hypochlorous acid (HOCl). The reaction is as follows: \[ \text{Cl}_2 + H_2O \rightarrow HCl + HOCl \]
- Statement II is also correct. The disinfection action of chlorine in water is primarily due to the formation of Hypochlorous acid (HOCl), which is a strong oxidizer and effective disinfectant. Thus, the correct answer is (1) Both Statement I and Statement II are correct.
