EXAMINATION IN CHEMISTEY. 
Maximum Number of Marks, 200. Pass Number, 100. 
I. General Chemistry. 
Wednesday, April lQth,from 10 a.m. till 1 p.m. 
1. ' Point out in what respects a mixture like atmosjiheric air differs 
from a chemical compound. Under what circumstances can niti'ogeu 
be made to imite chemically with oxygen ? 
2. Explain the changes effected in atmospheric air by burning 
sulphur in it. Give some account of tlie properties of the compound 
of sulphur produced in this way. Why does it stop acetification ? 
3. What gases are usually dissolved in freshly fallen rain-water ? 
Explain how they may be detected in such water and distinguished. 
4. Name the chief natural products containing potassium, and state 
the general composition of each. Distinguish those which are 
soluble in water ; and explain how you can get into a soluble form 
those which are insoluble in water. 
5. Define a neutral salt. 100 measures of a solution of sulphuric 
acid are found to dissolve 20 grains of calcium carbonate and no more : 
calculate how much acid was in the solution. (0 : S : C : Ca = IC : 
32 : 12 : 40.)
