Main findings • The lead nitrate/potassium iodide and cobalt chloride/ammonium hydroxide reactions both formed bifurcations. The cobalt chloride/ammonium hydroxide reaction was then investigated under different conditions until discernable Liesegang rings had formed. • It was found that the rate of diffusion of ions was increased when a D

ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements
