Which of the following statements concerning the attraction of ions to polar molecules is/are correct? 1. the force of attraction between an ion and a polar molecule is inversely proportional to the square of the distance between the center of the ion and the oppositely charged pole of the dipole. 2. the higher the ion charge, the stronger the attraction between the ion and a polar molecule. 3. the greater the magnitude of the dipole, the greater the attraction between the ion and a polar molecule.
