VISUALIZATION The Structure of Water Dipole moment 104.38-7 St H H Check d Van der Waals radius of hydrogen=0.12 nm Covalent bond length = 0.095 nm Van der Waals radius of oxygen = 0.14 nm What does it mean to say a molecule is dipolar? There is a local separation of charge. The distribution of partial charges is asymmetric. Partial positive and partial negative charges coexist. The molecule is liquid. (1 of 2)
VISUALIZATION Two Ways of Looking at Buffers pH 10 ONA 6 0.5 1.0 Equivalents of OH" added HA A PH 188 6 4 0 0.0 05 1.0 Equivalents of H* added [References] HA Buffers are weak conjugate acid-bases that have the ability to adsorb or release hydrogen ions in response to an outside addition of acid or base so that the pH of the solu not change appreciably. The effective range of buffers is approximately one pH unit above and one pH unit below the pk, of the buffer. The buffering capacity is determine concentration of the buffer and its pK₂.
