  1. Powerpoint Slides to AccompanyMicro- and Nanoscale Fluid Mechanics: Transport in Microfluidic Devices Appendix B Brian J. Kirby, PhD Sibley School of Mechanical and Aerospace Engineering, Cornell University, Ithaca, NY

  2. App B: Properties of Electrolyte Solutions • Electrolyte solutions can be described by use of terminolgy specific to solutions • The primary chemical reactions that control fluid flow in microfluidic systems are acid-base reactions, described by the Henderson-Hasselbach equation and the water dissociation reaction

  3. Sec B.2: Properties of Electrolyte Solutions • Electrolyte solutions are described in terms of molar concentration, molarity, normality, osmolarity, and ionic strength • Symmetric electrolytes have anions and cations whose valences are of equal magnitude

  4. Sec B.3: Acid-Base Chemistry • acid dissociation and recombination can be described with an acid dissociation constant, which is a special case of an equilibrium constant

  5. Sec B.3: Acid-Base Chemistry • The Henderson-Hasselbach equation relates the pH-pKa difference to the ratio of weak acid and conjugate base
