Abstract
IN recent publications1, it has been shown that the absorption of light by a mixture of two reacting substances is greater than the absorptions of the reacting substances considered separately. Thus the absorption in the visible and ultra-violet regions by a mixture of N/400 aqueous iodine and 2N potassium oxalate is much greater than the light absorption by N/800 aqueous iodine and N potassium oxalate taken separately. This relation has been observed with numerous chemical reactions taking place in aqueous solutions.
