Question

Consider the following statements:

Statement I: Activated carbon is a good and an attractive tool to remove pollutants from effluent streams and to remediate contaminants from various industries.

Statement II: Activated carbon exhibits a large surface area and a strong potential for adsorbing heavy metals.

Statement III: Activated carbon can be easily synthesized from environmental wastes with high carbon content.

Which one of the following is correct in respect of the above statements?

1. A. Both Statement II and Statement III are correct and both of them explain Statement I (Correct answer)
2. B. Both Statement II and Statement III are correct but only one of them explains Statement I
3. C. Only one of the Statements II and III is correct and that explains Statement I
4. D. Neither Statement II nor Statement III is correct

Correct Answer

Option A — Both Statement II and Statement III are correct and both of them explain Statement I

Detailed Solution & Explanation

The correct answer is Both Statement II and Statement III are correct and both of them explain Statement I.

Key Points

• Activated carbon's large surface area allows it to adsorb a wide range of organic and inorganic pollutants including heavy metals (Statement II explains I).
• It can also be synthesised from agricultural and industrial waste materials rich in carbon content, such as coconut shells, rice husks, and sewage sludge (Statement III explains I).
• Both II and III correctly explain Statement I.
