Editor's Notes
"Payne No. 1-- Variation 1. Immersed in a 6" evap. Dish in solution 2 prts. H2SO4 & 1 prt. HNO3 the 20 reg 16 C.P. Carbons that had been treated as per exp. Payne No. 1 & applied heat directly to dish. As the solution reached boiling point a violent ebullition took place around carbons, (gas being given off). Some carbon seemed to dissolve turning the acid dark & also the vapor. In about 3 min. action around Carbons ceases & solution clears off to a light green, chlorine color, Boiled to 1/2 vol. cooled to temp. of air slowly. Washed Carbons in H2O & dried by gentle heat. Carbons were not bent. Turned slightly darker, losing shiny appearance.
