Membrane Potentials in the Donnan Equilibrium
(The diagram gives, however, no indication of the hydrostatic pressure due to the liquid in the manometer tube, which is a necessary condition for equilibrium. For further details of the experiments Loeb's original papers and book s may be consulted.) AH and BH represent hydrogen electrodes; AK and BK, calomel electrodes connected to the solutions by saturated KC1. Loeb measured the potential d...
متن کاملMembrane Potentials in the Donnan Equilibrium. Ii
Measurements were made of electromotive force in the Donnan equilibrium of systems containing dilute solutions of protein and acid. Removal of the membrane produced a decrease of no more than 2 to 4 mv. in electromotive force, while the membrane potentials, as estimated by the usual arbitrary assumption, were of the order of 12 to 34 mv. Ion ratios, as calculated from analyses for total chlorid...
متن کاملNote on Donnan Equilibrium and Osmotic Pressure Relationship between the Cells and the Serum
In a paper on the factors controlling the electrolyte and water distribution in the blood Van Slyke, Wu, and McLean (1) based their mathematical deduction on three fundamental postulates: (1) Approximate neutrality of the blood reaction; sum of base cations equals sum of anions. (2) Validity of Donnan’s law of membrane equilibrium. (3) Equality of the osmotic pressure of the fluid within the ce...
متن کاملThe Donnan equilibrium: I. On the thermodynamic foundation of the Donnan equation of state.
The thermodynamic equilibrium between charged colloids and an electrolyte reservoir is named after Frederic Donnan who first published on it one century ago (Donnan 1911 Z. Electrochem. 17 572). One of the intriguing features of the Donnan equilibrium is the ensuing osmotic equation of state which is a nonlinear one, even when both colloids and ions obey Van 't Hoff's ideal osmotic pressure law...
متن کاملChemical structure of erythrocytes with emphasis on Donnan equilibrium.
Hemoglobin is a major constituent of erythrocytes. Because it is non-diffusable and confined within a cell membrane and because of its buffering powers, three major physiochemical equilibria are involved in any acid or base change in blood. Ionic, osmotic and Donnan balance must be main tained.16 During the acidosis phase of cell ular respiration and increasing Pco2, bi carbonate enters eryt...
