Given below are two statements:
Statement (I): When the pH value of a hazardous waste is high or low, it should be treated to make it neutral before its disposal.
Statement (II): To neutralize hazardous waste with a low pH value, sulfuric acid and hydrochloric acid are added to it.
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

Show answer & explanation
Correct answer: C
Statement (I) is correct because hazardous waste with extreme pH levels must be neutralized before disposal to prevent environmental damage. Statement (II) is incorrect because low pH indicates acidity, which requires a base for neutralization rather than adding more acids like sulfuric or hydrochloric acid. Therefore, Statement I is correct but Statement II is incorrect.
