Look at the structure of a soap molecule, and explain what happened when you added soap to your oily hands and put your hands under the water for the solubility lab. Why could you wash the oil off your hands with soap and water? You should use chemistry concepts including structure, polarity, and intermolecular forces to explain your answer. attached is the lewis structure of a basic soap molecule. There are covalent bonds between all carbons, hydrogens, and oxygens. However, there is an ionic bond between oxygen and sodium ions.
