Explanation:
Detailed explanation-1: -Wood charcoal is used to decolorize sugar because it has a highly porous structure, providing a large surface area for adsorption. Therefore it adsorbs colored material from sugar.
Detailed explanation-2: -Decolorizing carbon, also called activated charcoal, is finely divided carbon often used to decolorize a solution. The small particles of decolorizing carbon provide a large surface area to which large colored molecules may become adsorbed.
Detailed explanation-3: -Charcoal is used as a decolorizing agent in the sugar industry.
