(a) The gaseous mixture is passed through a little water. Hydrogen chloride is -thereby completely removed, because the gas is highly soluble in water and, furthermore, the. solu- hility of hydrogen chloride in water is more than a hundred times that of chlorine gas.
(b) Carbon dioxide is removed by passing the
gaseous mixture through soda-lime or caustic soda solution in accordance with the following
Na2CO3 Hg G
reaction:
But there is no reaction between carbon- mon- oxide and caustic soda at this temperature. c) By passing the gas through a lime tower on
a U-tube containing quick-lime, the water vapour is completely taken up by the quicke lime to form slaked lime, according_to_the equation,

6. (a) Describe in note form now you would prepare an approximately N/10 solution of hydrochlorio acid, given some concentrated acid' which is about ten times normal; then say how you would standardise it accurately against stána¬ ard sodium, carbonate solution..
(b) 125 cc hydrochloric acid were axiuted to 500 cc. and then titrated against decinormal sodium carbonate solution. If 20 cc, of the carbonate solution required 14,6 cc, of the diluted acid for neutralisation, find :
11/ the weight of acid in the original sol-
ution, ii/ the volume of the diluted actd required
to make up a litre of decinormal strength.
(c) 0.288 gm. of a metal was dissoved in 50 ml.
of N hydrochloric acid. The excess of acid required 13 ml, of a sodium hydroxide solu−, tion for neutralisation, 25 ml, of the N hydrochloric acid
the hydroxide.
Calculate:
neutralised_12.5 ml, of.
i/ the equivalent or the metal. 11/ the volume of hydrogen evolved when;
measured at -741 mm. and 13 C.. 「andidi/ the concentration of the sodium hydroxide in gm./litre.
7. The following six pairs of substances are
given;
!
(a) Black copper oxide and manganese dioxide. (b) Anhydrous sodium carbonate and sodium
bicarbonate.
Red mercuric oxide and red lead, Ammonium chloride and potassium chloride. Sodium sulphate and sodium sulphite. Potassium nitrate and potassium nitrita. For each of these pairs describe one test only
which, when applied to each of the two subs- tances in a pair, will enable you to distin-. guish between them.
Give-such explanation of the tests as you are
able.
8. Describe how you would show by experiment the
presence of:
oxygen in nitric acid,
copper, in copper nitrate,
nitrogen in ammonia,
(d) carbon in calcium carbonate,
(●) chlorine in potassium chlorate.
