2. Same question in regard to: (a) ammonia, (b) hydrogen 

 sulphide, and (c) hypochlorous acid. 



3. Same question in regard to: (a) an acid salt, (b) a hydrate, 

 (c) nitrogen tetroxide, (d) bromine, (e) sulphur trioxide, (f) hy- 

 drogen peroxide, (g) ammonium nitrate, (h) carbon dioxide. 



4. Same question in regard to (p. 379) : (a) a bromide, (b) an 

 iodide, (c) a nitrate, (d) bleaching powder, (e) sulphur dioxide, 

 (f) carbon monoxide, (g) a silicate, (h) a sulphate, and (i) a phos- 

 phate. 



5. Same question in regard to (p. 380) : (a) cone, and (b) dil. 

 sulphuric acid, (c) cone, and (d) dil. nitric acid, (e) cone, and (f) 

 dil. hydrochloric acid, (g) hydrobromic acid, (h) hydriodic acid, 

 (i) phosphoric acid, (j) sulphurous acid. 



6. Same question in regard to: (a) chlorine-water, (b) alcohol,

8. Why does sodium sulphide smell of H 2 S (see pp. 118, 369)? 



9. When ammonium nitrate is heated in a test-tube, the gases 

 evolved do not relight a glowing splinter. How can this be 

 reconciled with p. 315?
