डिफरेंटशिएट बिटवीन सॉप एंड डिटर्जेंट
Answers
Answer:
Soaps-
Soaps are potassium or sodium salts of a carboxylic acid having a long aliphatic chain attached to it.
They are surfactants (compounds that reduce the surface tension between a liquid and another substance) and therefore help in the emulsification of oils in water.
Soaps are generally prepared via the saponification of fats and oils.
The carboxylate end of the soap molecule is hydrophilic whereas the hydrocarbon tail is hydrophobic.
Detergents-
Detergents are the potassium or sodium salts of a long alkyl chain ending with a sulfonate group.
They are soluble in hard water.
This solubility is attributed to the fact that the sulfonate group does not attach itself to the ions present in hard water.
Commonly, anionic detergents such as alkyl benzene sulfonates are used for domestic purposes.
What is the difference between soap and detergent?
Soaps are the sodium salts of carboxylic acids in long chains. Sodium salts of long-chain benzene sulphonic acids are detergents. Soaps are biodegradable while some of the detergents can not be biodegraded. Soaps have relatively weak cleaning action, whereas detergents have a strong cleaning effect.
