Word bank: oxygen, hydrogen, ionic, polar, nonpolar, hydrophilic, hydrophobic, hydrophobic force Question: Because water molecules are polar, anything________. or __________can dissolve in it (we call these substances to be ____________). In the case of salt (NaCl), it dissociates into Na+and Cl- in water. Na+ is positively charged therefore can interact with the __________________portion (slightly more negative) of the water molecules, whereas the negatively charged Cl- can interact with the ________________ portion (slightly more positive) of the water molecules. Vegetable oil, on the other hand, is a __________________ molecule, hence it's ______________ Hydrophobic molecules do not interact with water and are excluded from water by______________ , forcing the oil to cluster together when added into water.
