Ionic Radius and Ionic Efficiency
1. It has been shown in preceding papers that when we separate solutions of electrolytes from pure water by collodion membranes the ions with the same sign of charge as the membrane increase while the ions with the opposite sign of charge diminish the rate of diffusion of water from the side of pure water to the side of solution; and that the accelerating and depressing effects of these ions on...
متن کاملIonic Radius and Ionic Efficiency. by Jacques Loeb
When pure water is separated from solutions of electrolytes of not too high a concentration (generally below ~/4) by a collodion membrane, the initial rate of diffusion of water through the membrane from the side of pure water to that of the solution is influenced in a characteristic way by ions and the following rules have been found to govern this influence. 1. Ions possessing the same sign o...
متن کاملRelationship between Ionic Radius and Pressure Dependence of Ionic Conductivity in Water
Experimental measurements of ionic conductivity in water are analysed in order to obtain insight into the pressure dependence of limiting ionic conductivity of individual ions (λ) for ions of differing sizes. Conductivities of individual ions, λ do not exhibit the same trend as a function of pressure for all ions. Our analysis suggests that the effect of pressure on ionic conductivity depends o...
متن کاملApproaches to estimate the ionic radius of hydrated Po
Due to the relativistic stabilisation of 6p1/2 electrons polonium – usually present in the 4+ oxidation state – can be reduced to the 2+ oxidation state. This cation has – outside it's filled [Xe]4f5d electron shells two electron pairs: 6s and 6p1/2. No information is available about the ionic radius of Po and about it's coordination number of water molecules in aqueous solutions. The measureme...
متن کاملIonic gradients, membrane potential and ionic currents
The neuronal plasma membrane delimits the whole neuron, cell body, dendrites, dendritic spines, axon and axon terminals. It is a barrier between the intracellular and extracellular environments. The general structure of the neuronal plasma membrane is similar to that of other plasma membranes. It is made up of proteins inserted in a lipid bilayer, forming as a whole a ‘fl uid mosaic’ ( Figure 3...
