Yellow glycerine is made into white, using

ANS:A - activated carbon

Yellow glycerine is made into white using activated carbon. Yellow glycerine is made into white using activated carbon for several reasons:

1. Adsorption Properties:

• Impurity Removal: Activated carbon has a high surface area and porous structure, allowing it to effectively adsorb impurities, color compounds, and contaminants present in yellow glycerine.

2. Decolorization Process:

• Color Elimination: During the treatment process, yellow glycerine is passed through activated carbon filters or columns, where the carbon adsorbs colorants and other unwanted substances, resulting in a clearer, colorless product.

3. Chemical Stability:

• Non-reactive Nature: Activated carbon is chemically stable and does not react with glycerine, ensuring that the purity and quality of the glycerine are maintained during the decolorization process.

4. Cost-effective:

• Economical Solution: Using activated carbon for decolorization is a cost-effective method compared to other chemical treatments, making it a preferred choice in the industry.
