Part B Soaps form micelles when added to water and can be used to remove dirt or grease from surfaces. The dirt or grease molecules get trapped inside the micelle and can be easily washed away using water. Micelles de Water Which of the following statements are correct concerning the use of soap to remove dirt or grease from an object? Check all that apply. View Available Hint(s) The nonpolar end of the soap attracts the water molecules surrounding it. Soaps have a polar end and a nonpolar end. The polar end of a soap particle interacts with the water molecule. The dirt particles are generally nonpolar. The hydrocarbon chain is attracted to the water molecules. Soaps are fat molecules. The core of a micelle is formed by hydrocarbon chains. Submit Previous Answers X Incorrect; Try Again; 3 attempts remaining
