Chapter 2. Aqueous Chemistry

Chapter 2. Aqueous Chemistry. 4 Important weak interactions. I. Weak interactions in aqueous solutions. A. Hydrogen Bonds. H-O bonds in H 2 O are polar. differing electronegativities lead to partial charges (-O and +H) = electric dipole. Takes about 20 kJ/mol to break H-bonds.
