The formation of a rhythmic band structure known as Liesegang rings, when silver ions diffuse into gelatin containing chromate ions is a well-known phenomenon. The object of this research project is to make a detailed study of another diffusion phenomenon obtained in the presence of mercury vapor. The emphasis of this thesis is on the quantitative aspect. The author has been concerned with the cause and composition of radial lines produced when silver ions diffuse through chromated gelatin in the presence of mercury vapor. A number of variables related to this project, such as length of reaction time, concentration and nature of reactants and free area of mercury exposed, have been studied and will be discussed in this thesis.
