1/20 Quiz 2 due @ 9 AM Thursday Chemistry Assessment Due Friday Clicker: in chemistry we learned that ionic bonds were strong; here you said they are weak. Why? Because in biology things happen in water Clicker: equal sharing of electron pairs in a covalent bond = Nonpolar covalent bond Unequal sharing of electron pairs in a covalent bond = Polar covalent bond 6. Capillary Action and Surface Tension Due to hydrogen bonding 7. Ionization Dissociation into acid (hydronium ion) And base (hydroxyl ion) Unusual properties of water 1. High heat capacity 2. High heat of vaporization 3. High heat of fusion 4. Most dense at 4C 5. High dialectric 6. Capillary action and surface tension 7. Ionization Clicker: Most aquatic animals are ectotherms because of water’s: high heat capacity (loose heat to the water) pH – a review Some basic principles (ACIDIC) Acids, Bases, and Salts Acid produce H+ ions HCl- H+ and Cl- Bases produce hydroxide ions NaOH - Na+ and OH- Salts produce neither NaCl - Na+ and Cl-
