Which of the following statements about detergents is correct?
ADetergents are sodium or potassium salts of fatty acids
BDetergents form scum in hard water
CDetergents are acidic in nature
DDetergents are synthetic and do not form scum in hard water
Step-by-Step Solution
Step 1: Understand detergent properties
Detergents are synthetic cleaning agents designed to work well in hard water.
Step 2: Analyze options
Detergents are not salts of fatty acids (that's soap); they do not form scum in hard water; detergents are generally neutral or slightly basic, not acidic.
Step 3: Explain why other options are wrong
Soaps are sodium or potassium salts of fatty acids, not detergents; detergents do not form scum; detergents are not acidic.
Final Answer:
Detergents are synthetic and do not form scum in hard water → Option D
Quick Check:
Detergents = Synthetic, no scum in hard water ✅
Quick Trick:Detergents work well in hard water unlike soaps.
Common Mistakes:
MISTAKES
