Soaps are sodium or potassium salts of which type of acids?

Answer and explanation

Correct answer: Long-chain fatty acids

Soaps are sodium or potassium salts of long-chain fatty acids, such as stearic acid. Their long hydrocarbon chain associates with oil or grease, while the ionic end interacts with water, enabling cleansing action. In contrast, salts of short-chain carboxylic acids lack the long hydrophobic chain characteristic of soaps.
