MCQ
What is the side product of soap industry?
- ASodium Hydroxide
- BEsters
- CEthanol
- ✓Glycerol
✓
Answer
Correct option: D.
Glycerol
Soaps are prepared from vegetable oils and animal fats, containing tri$-$esters called triglycerides.
These triglycerides can be converted to soap by treating them with a strong base, which accelerates cleavage of the ester bond and releases the fatty acid salt and glycerol.
