Total Sulphur in 2 cc of solutions .1274 grams or 5.25 percent 



Sulphur in solution as H SC>4 in 2 ccS .C960 grams or 3.96 



percent 



Sulphur in solution combined to Nicotines .03 1 4 grams or 1.29 



percent 



Trace of Lime in the solution. 



Some of the Nicotine in the solution is not combined as sulphate 



although there was an excess of HZ SO4 present. The Nicotine 



may be combined in some way with the organic matter present. 



Quite a little organic matter is present in this solution. 



3. Nicotine solution called Nico-fume. 



Specific Gravity of the solution at 15 C.S 1.0139 



Per cent of Nicotine in solutions 36.04 



Per cent of Nicotine combined as sulphate 6. 1 5 



Total sulphur in 2 cc, of solutions .0123 grams or .60 per cent. 



Sulphur in solution combined to Nicotines .0123 grams. 



There is no lime present in the solution. 



Solution is Alkaline. 



Alkalinity (Phenolthaloin as ind.) expressed as NaOHss .24 p. ct. 



Alkalinity (Cochineal as Indicator) expressed as NaOHsl.Ol 



percent 



The increased alkalinity with cochineal as indicator may be due 



entirely to free Nicotine present. Somtion does not contain hardly 



any organic matter, and is not very thick. 



4. Nicotine solution called Rextract, which is a mixture of Nicotine and 



Lime-sulphur containing some sediment. 



Hydrogen sulphide is given off of the solution abundantly. 



Total sulphur in 2 cc. of the solutions .2822 grams. 



Total Lime (CaO) in 2 cc. of the solutions . 1 84 1 " 



Total Calcium in 2 cc. of the solutions .1315 grams 



Hard to obtain a uniform sample of the solution and sediment 



5. Grasselli's Arsenate of Lead-Paste, and Hemingway's Lead Arsenals 



Both of these were acid. 



(Grasselli's) Acidity expressed as H2 SO4 sO.31 percent. 



(Hemingway's) sO.37 percent. 



6. Solution of Hydrogen Peroxide. 



Total Sulphur in 50 cc. of the solutions .0040 grams. 

 Total Lime (CaO) in 50 cc. of the solutions none 



Experiment No. 1 was to determine the amount of sulphur and Calcium 

 lost from the Lime-sulphur solution by mixing 2 cc of the Nicotine compound 

 with a dilute Lime -sulphur of the dilution 1:10.
