Discussion
Detergents used for cleaning clothes and utensils contain?
Answer: C
Detergents contain sulphonates - usually the sodium salts of long-chain alkyl benzene sulphonic acids.
The sulphonate head does the job the carboxylate head does in soap, but its calcium and magnesium salts are soluble, so a detergent lathers in hard water where soap forms a scum.
