Polar molecules will be attracted to each other by either hydrogen bonding or dipole-dipole interactions. These intermolecular forces are made possible by a large difference in electronegativity values for two atoms bonded to each other. In water, the electronegativity difference between oxygen (3.5) and hydrogen (2.1) is 1.4 (3.5-2.1=1.4).Solution: Freundlich equation or Freundlich adsorption isotherm gave an empirical relationship between the quantity of a gas adsorbed into a solid surface and the gas pressure. Oct 24, 2012 · See tutors like this. Since KCl is a neutral molecule, the sum of the oxidation states of the atoms equals zero. We know that potassium (K) has an oxidation of +1 since it is a group 1 element. So, K +1 Cl -1 ===> KCl 0 OR KCl. Thus, the charge on potassium (K) in KCl is +1. Upvote • 2 Downvote.
