Draw 3 submicroscopic (molecular level) pictures: (1) pure water (use 5 water molecules) (2) CaCl, solution (use 5 water molecules and 1 unit of CaCl2) (3) KBr solution (use 5 water molecules and 1 unit of KBr) In each picture, show the intermolecular forces acting on the molecules (hydrogen bonding and ion-dipole). Use your illustrations to explain the freezing point depression you observed. Upload your drawings and explanation as a pdf file
