The Extension of the Spectrum Beyond the Schumann Region

Abstract

LYMANgeneral solutes may be treated as normal or 'perfect' solutes is much more persistent.The magnitude of the deviation of the strong electrolyte from the normal behavior depends greatly upon the terms in which this devia- tion is expressed.The equilibrium expression C?/C, increases with the concentration.Thus for potassium chloride it increases from 0.026 at 0.001 normal to 0.55 at 0.1 normal, an increase of 21 fold.The results given in the table show that this behavior is accounted for by a deviation of 3.3% in the osmotic pressure of the ions and of 37% in that of the undissociated molecules.The percentage deviation when expressed as here in terms of osmotic pressure is smaller than when it is expressed, as Lewis6 has done, in terms of activity; this follows from the logarithmic relation between the two.A more thorough study of these topics is appearing in The Journal of the American Chemical Society.
