EXAMINATION IN CHEMISTRF. 
Maximum Number of Marks, 200. Pass Number, 100. 
A. General Chemistry. 
Thursday, May loth, from 10 a.m. till I p.m. 
1. How can nitrogen be distinguished from other gases ? How can it be 
brought into combination with oxygen ? How can you detect the presence of 
nitric acid, and of nitrous acid ? 
2. Mention gases easily soluble in water, and others which arc but little 
soluble. State how the solubility of a gas in water is affected by temperature 
and by pressure ; and give facts, or experiments, in proof of your statement. 
What are the gases usually held in solution in freshly fallen rain ? 
3. Describe the preparation of hydrochloric acid, and explain the chemistry 
of the process. Explain the action of that acid with caustic soda, metallic 
iron, red lead, and nitric acid, respectively. 
4. What are the chief sources of ammonia ? State the composition s by weight 
and by volume, of ammonia ; and give an account of its properties. How can 
you obtain ammonia from the sulphate, and what weight of ammonia will 
1,000 grs. of the sulphate give ? 
5. Describe the preparation and properties of sulphuretted hydrogen. Ex- 
plain its action with (1) white lead, (2) slaked lime, (3) ferric chloride. 
6. Explain the chemistry of lime-burning, and give the chemical characters 
of lime. Explain the differences in the characters of limes obtained from 
different kinds of limestone. What is the chemical action of slaked lime with 
(1) sodium carbonate, (2) ferric chloride, (3) common sodium phosphate ? 
7. Describe the chief characters of zinc ; and the effects of acids, alkalies, 
and exposure to the weather, upon it. How is iron galvanised ? 
8. State the chemical composition of starch, and describe its chief properties 
and its mode of occurrence. Explain the relations between starch, gum, sugar, 
and cellulose. 
9. Explain the general chemical constitution of fats. How do mineral oils, 
and such oils as oil of turpentine, dilfer from fats ? Explain the chemistry of 
the conversion of fat into soap.
