A Contribution to the Physical Analysis of the Phenomena of Absorption of Liquids by Animal Tissues (Classic Reprint) - Tapa blanda
Sinopsis
This book delves into the phenomena of the exchange of liquids separated by semipermeable membranes, specifically focusing on the absorption of liquids by animal tissues. The author challenges the prevailing notion that osmotic pressure alone governs these processes, proposing instead a multifaceted model that incorporates both osmotic pressure and ionic effects. Through a series of meticulously designed experiments, the author demonstrates the varying osmotic values of different salt solutions and their impact on the absorption and swelling of muscle tissue. The findings challenge the simplistic view of osmotic pressure as the sole determinant of absorption and shed light on the complex interplay between osmotic and ionic forces in biological systems. The book's insights are not only scientifically groundbreaking but also have significant implications for our understanding of cell physiology and the mechanisms underlying fluid exchange in living organisms.

Excerpt from A Contribution to the Physical Analysis of the Phenomena of Absorption of Liquids by Animal Tissues
Van't Hoff, applying certain facts brought out by Traube and Pfeffer regarding the influence Of semi-permeable membranes upon processes of osmosis, Showed that sub stances in solution Obey the ordinary laws Of gases, as brought forth by Boyle, Henry, gay-lussac, and Avogadro. In consequence Of this similarity between gases and sub stances in solution, the latter will exert a pressure upon the walls Ofa containing vessel equal to the pressure which the dissolved substance would exert were it present in the gaseous form under the same conditions Of temperature and molecular aggregation. Whether this pressure, which van't Hoff calls osmotic pressure, be due to the impacts Of the dissolved particles against the walls Of the containing vessel, as the kinetic theory Of gases would demand, or whether it be an expression Of the attraction Of the dissolved particles for water, concerns us, in these experiments, only in so far as our work has to do with the dynamics Of the process Of absorption.

Excerpt from A Contribution to the Physical Analysis of the Phenomena of Absorption of Liquids by Animal Tissues
The following paper is, m the title indicates, intended to be a contribution to the physical analysis of phenomena of absorption by living tissues. That the older experiments on absorption could not lead to any satisfactory explanation of tho processes involved seems evident from the fact that only recently has there been discovered one of the most fundamental theories concerning the exchange of liquids separated by membranes, more or leas semi-permeable. Only such papers can be expected to throw a light on this subject as take cognizance of this theory of osmotic pressure.
Van't Hoff, applying certain facts brought out by Traube and Pfeffer regarding the influence of semi-permeable membranes upon prooesses of oemosia, showed that substances in solution obey the ordinary laws of gases, as brought forth by Boyle, Henry, Gay-Lussac, and Avogadro. In consequence of this similarity between gasce and substances in solution, tho latter will exert a pressure upon the walls of a containing voeeol equal to tho pressure which the dissolved substance would exert were it present in the gaseous form under the same conditions of temperature and molecular aggregation. Whether this pressure, which van't Hoff calls" osmotic pressure," be due to the impacts of the dissolved particles against the walls of the containing vessel, as the kinetic theory of gases would demand, or whether it be an expression of the attraction of the dissolved particles for water, concerns us, in these experiments, only in so far as our work has to do with the dynamics of the process of absorption.
From these facts it is evident, as van't Hoff shows, that the pressure of a substance in solution depends both upon the concentration of the substance and upon the temperature at which the observation is made. By the concentration we mean, not the number of molecules, as such, contained in a definite amount of the solvent, but, rather the total number of "active" particles contained in a definite (usually 1 liter) amount of solvent This fact was made clear by the endeavor to collate tho pressures of various salt solutions with those of organic substances, or, in other words, of electrolytes with those of non-electrolytes. Clausius had shown that the molecules of substances conducting electricity, viz., of electrolytes, are dissociated into ions, which have a movement independent of one another.
