Question:
Which among the following is used in detergent?
Which among the following is used in detergent?
Show Hint
Detergents differ from soaps as they work well in hard water and are often based on synthetic surfactants like sodium lauryl sulphate.
Updated On: Mar 24, 2025
- Sodium acetate
- Sodium stearate
- Calcium stearate
- Sodium lauryl sulphate
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Role of Detergents
Detergents are surfactants that help in emulsifying grease and oils, making them soluble in water.
Common detergents include anionic detergents such as sodium lauryl sulphate (\( {CH}_3 ({CH}_2)_{10} {CH}_2 - {OSO}_3^-{Na}^+ \)).
Step 2: Why is Sodium Lauryl Sulphate Used?
Sodium stearate is used in soaps, not in detergents.
Calcium stearate is insoluble and not used in detergents.
Sodium lauryl sulphate is widely used in detergents due to its excellent cleansing properties.
Thus, the correct answer is (D).
