BIO311C 1nd Edition Lecture 2 Outline of Last Lecture - Atoms and Elements - Bonding - Hydrophobic and HydrophilicOutline of Current Lecture - Water Properties Current LectureNo hydrogen bonding occurs in gaseous water because the water molecules are too far apartA moderate amount of hydrogen bonding occurs in liquid water Strong hydrogen bonding occurs in solid state of water. At 4 C, water is most dense. At 0 C, water is the least dense. Water can be ionized into hydronium and hydroxide ions but it reverses back to its original state because the ionized state isn’t stable. PH: Measure of proportion of H+ ions to OH- ions Negative log10 of H+ concentration PH = -log[H+]Buffer: Neutralizes the PH of blood Accepts or donates H+ protons according to the situationThese notes represent a detailed interpretation of the professor’s lecture.
