Studies on the Regulation of Osmotic Pressure
1. In pure gelatin solutions the conductivity of the solution increases with increasing concentrations, regardless of the hydrogen ion concentration. The actual value of the specific conductivity is greater at that reaction where the degree of ionization is greater. 2. The addition of gelatin in increasing concentrations to a 0.6 per cent sodium chloride solution affects the conductivity of tha...
متن کاملCALCULATION OF OSMOTIC PRESSURE USING A CLOSED SYSTEM MODEL
In this work we have used a closed system model to derive an analytical equation for the osmotic pressure of two component electrolyte and non-electrolyte solutions. In order to do so, we have used an equation of state, known as the dense system equation of state (DSEOS), for the model system. Based on the model, a new definition is given for the osmotic pressure of a closed system. Good ag...
متن کاملNew Osmosis Law and Theory: the New Formula that Replaces van't Hoff Osmotic Pressure Equation
Preamble van't Hoff, a world-renowned scientist, studied and worked on the osmotic pressure and chemical dynamics research to win the first Nobel Prize in Chemistry. For more than a century, his osmotic pressure formula has been written in the physical chemistry textbooks around the world and has been generally considered to be "impeccable" classical theory. But after years of research authors ...
متن کاملEffects of buoyancy and of magnetic forces on osmotic pressure.
The commonly held view that the mechanism of osmotic pressure is a mass action effect at the semi-permeable membrane has recently been challenged by several authors who propose that solute molecules, in bombarding the free surface of the solution, subject the solvent to a negative hydrostatic pressure. Thus, they argue that osmotic pressure is a purely hydrostatic phenomenon. Experimental findi...
متن کاملThe effect of osmotic pressure on succinoxidase activity.
Structural damage to mitochondria is known to cause diverse effects on the activities of enzymes linked to those particles (2). Some systems are activated or have their activity enhanced by many procedures damaging to the mitochondria, while others suffer considerable loss in activity (2). Hypotonic solutions are frequently employed to disrupt structural integrity, and, when increases in activi...
