Chemistry 2004 JAMB Past Questions - Question 31: The allotrope of carbon used in the decolourization Of sugar is

Correct Answer

C

Explanation

The allotrope of carbon commonly used in the decolorization of sugar is activated carbon. Activated carbon is a form of carbon that has been processed to have a large surface area, making it effective for adsorption of impurities, including color compounds, from liquids or gases. In the sugar industry, activated carbon is often used in the decolorization or purification of sugar solutions. It adsorbs impurities and pigments, resulting in a clearer and more colorless sugar solution.

It's important to note that activated carbon is not a specific allotrope of carbon but rather a form of carbon that has undergone activation to increase its porosity and surface area, enhancing its adsorption capabilities.
