Abstract

The change in rate of reduction of silver from solutions of varying silver ion and silver sulfite complex by hydroquinone and metol was studied. The silver ion concentration was varied and the silver complex concentration was held constant. The rate was found proportional to the square root of the silver ion concentration for development by hydroquinone. The silver complex concentration was varied and the silver ion concentration was held constant. The rate of reduction increased as the complex concentration increased for both hydroquinone and metol developing agents, showing that the complex was being reduced. The rate appeared to be proportional to the silver complex concentration. The reaction rate was proportional to the surface area of the silver particle and was not found to be controlled by diffusion.
