VI.—The Significance of Maximum Specific Electrical Conductivity in Chemistry
Published online by Cambridge University Press: 06 July 2012
Extract
The first step made in this investigation was the recognition of increased specific electrical conductivity as a general characteristic of photochemical action. It was argued that if there be any common characteristic in photochemical changes it must be found in the simplest as well as in the more familiar and more complex reactions which are characteristic of the metabolism of plants.
No chemically simpler case suggested itself than the increase in electric conductivity of crystalline selenium under the influence of light. This change might indeed be held almost to lie outside the range of chemistry proper, and to belong to the class of change often spoken of as merely physical change. But no sharp line can be drawn between physical and chemical changes, and the clue proved most useful.
