What is the chemical formula of soap?
Asked by Kalita Padmanath | 03 Jun, 2014, 07:55: PM
answered-by-expert Expert Answer
  • Soaps are sodium and potassium salts of long chain fatty acids consisting 12 to 18 carbon atoms.
  • Soaps are denoted by the general formula RCOO-Na+, where R is any long chain alkyl group consisting 12 to 18 carbon atoms.
  • Some common examples of fatty acids that are used in soaps are stearic acid having chemical formula C17H35COOH, palmitic acid having chemical formula C15H31COOH.
  • So sodium salts of these acids are C17H35COO-Na+, C15H31COO-Na+.
