In this paper some experiments are described showing that chlorophyll reacts with certain oxidizing agents—especially with ferric salts —forming a yellow product, from which it can be easily regained, for instance, by the action of ferrous salts . Photoelectric measurements were made of the extinction curves of: I. The methyl alcohol solutions of chlorophyll (both the two chlorophylls a and b , and the “natural” mixture of the two ethyl chlorophyllides). II. The solutions of the same three substances after reaction with FeCl3. III. The same solutions “restored” by FeCl2.
