are the results of titration of ferrous 

 compounds expressed in terms of iron, 

 and those of sulfite as sulfur dioxide? 



9. In what does a simple titration 

 dififer from a residual titration ? Which 

 of these would you perform in the 

 determination of an insoluble base? 

 Why? 



10. Find the quantities of the pure 

 reagents in 500 cc. of each of the fol- 

 lowing V. S. (The figures represent 

 molecular weights) : 



2/N-sodium hydroxide (40.04). 

 N/2-sulfuric acid (98.09). 

 N/i-hydrochloric, 95% (36.47). 

 N/io-sodium thiosulfate (248.24). 

 N/20-permanganate (316.06). 



11. Calculate the per cent, of Ba 

 Cl2-(-2H20 (244.32) in a sample in the 

 titration of which were used : sample, 

 0.32 g., N/io AgN03 V. S., 30 cc, 



N/io KSN V. S., 5 cc. 



12. A solution of KOH is found to 

 be 106.5% normal, (a) How many 

 cc. of a 92% N/2 V. S. of an acid will 

 be neutralized by 22 cc. of it? (b) How 

 much water must be added to convert 

 800 cc. of the solution into a N/i V. S. ?

 Nitrous Ether 

 Adonis 



Veratrum 

 Resin of Jalap 

 Tobacco

2. Which of the following doses 

 would you regard as decidedly dan- 

 gerous for an adult, under ordinary 

 conditions? 



I oz. Fluidextract of Spigelia 



i/io grain of Aconitine 



I fl. dr. Tincture of Veratrum 



10 minims Oil of Cinnamon 



15 grains of Asafoetida 



% grain of Codeine 



8 oz. of Brandy 



I dr. of Copper Sulphate 



30 grains of Blue Mass 



8 oz. Syrup of Senna 



3. Give the symptoms and treatment 

 of poisoning by Nitro-glycerin. 



4. In case of each of the following 

 poisons, state whether it would dilate 

 or contract the pupil. This does not 

 refer to dilation due to collapse in final 

 stage, but to the direct action of the 

 poison. 



Hyoscyamine 



Eserine 



Opium 



Cocaine 



Nicotine 



5. Name the best physiological anti- 

 dote for each of the following: 



Strychnine 



Aconite 



Mercury 



Atropine 



Cocaine 



6. How would you distinguish be- 

 tween poisoning by alcohol and bella- 

 donna? What is the appropriate treat- 

 ment for each ?
