Abstract:

Ultraviolet light produces color changes in 2,3, 5-triphenyltetrazolium chloride solutions, it was believed important to explore this phenomenon in relation to different types of radiant energy. The experiments here reported are to be regarded as exploratory in nature. Ultraviolet light 3650 A to 2536 A reduces 2,3, 5-triphenyltetrazolium chloride in solution to its red formazan. The amount of reduction depends upon the intensity of the light source andor the time of exposure. The rate of formation of the red formazan increases with an increase in concentration of the salt solution. The reduction is influenced by pH and temperature. Alpha radiation and x radiation also reduce 2,3, 5-triphenyltetrazolium chloride to its red formazan. It is believed that this study is an experimental contribution to the theory of Weiss on radiochemistry of aqueous solutions. Author
