Aqua regia is a mixture of concentrated hydrochloric acid [3 parts] and concentrated nitric acid [1 part].

Frank Modern Certificate Solution for Class 10 Chemistry Chapter 8 - Study of Compounds-I: Hydrogen Chloride Page/Excercise 204

Solution 2010-2

(i) A = conc. H2SO4 B = NaCl

(ii) 

(iii) When a rod dipped in ammonium hydroxide is brought near the mouth of the gas jar, dense white fumes of ammonium chloride are produced.

(iv) Hydrogen chloride is denser than air. 

Solution 2010-3

Silver nitrate solution will give a white ppt. when added to dil. hydrochloric acid, and no change will be observed when it is added to dil. nitric acid. 

Solution 2011-1

Being highly soluble in water, hydrogen chloride gas is dried by conc. sulphuric acid.

Solution 2011-2

(i) Diagram to show the arrangement used for the absorption of HCl gas in water:

 

(ii) Such an arrangement is necessary to prevent back suction of water into the apparatus, and it provides a large surface area for dissolution of hydrogen chloride gas. 

(iii) Balanced chemical equations for the laboratory preparation of HCl gas:

Solution 2013-1

(i) Add silver nitrate solution to both solutions. Sodium chloride will form a curdy white ppt., whereas sodium nitrate will not undergo any reaction.

(ii) Hydrogen chloride gas gives thick white fumes of ammonium chloride when a glass rod dipped in ammonia solution is held near the vapours of the acid, whereas no white fumes are observed in case of hydrogen sulphide gas.

(iii) Ethene gas decolourises the purple colour of KMnO4, whereas ethane does not decolourise KMnO4 solution.

(iv) Calcium nitrate forms no ppt. even with addition of excess of NH4OH, whereas zinc nitrate forms a white gelatinous ppt. which dissolves in excess of NH4OH.

(v) Carbon dioxide gas has no effect on acidified KMnO4 or K2Cr2O7, but sulphur dioxide turns potassium permanganate from pink to colourless. 

Solution 2014-1

(i) The gas is HCl (hydrogen chloride) gas.

(ii) Extreme solubility of hydrogen chloride gas is demonstrated by the fountain experiment.

(iii) Ammonia gas is another gas which has the same property which can be demonstrated through this experiment.

Solution 2015-1

(i) Equation for the laboratory preparation of hydrogen chloride gas:

Although it is a reversible reaction, it goes to completion as hydrogen chloride continuously escapes as a gas.

The reaction can occur up to the stage of the formation of sodium sulphate on heating above 200°C.

(ii) The drying agent used in the laboratory preparation of hydrochloric acid is conc. sulphuric acid.

The other drying agents such as phosphorus pentoxide (P2O5) and quick lime (CaO) cannot be used because they react with hydrogen chloride.

2P2O5 + 3HCl POCl3 + 3HPO3

CaO + 2HCl POCl3 + 3HPO3

(iii) A safety precaution which should be taken during the preparation of hydrochloric acid:

Always wear chemical splash goggles, chemical-

resistant gloves and a chemical-resistant apron in the

laboratory during the preparation of hydrochloric

acid. 

Solution 2016-1

(a) HCl turns blue litmus red

Solution 2016-2

(i) When dil. HCl is added to lead nitrate solution and heated, it forms a white precipitate of lead chloride.

 Pb(NO3)2 + 2HCl PbCl2 + 2HNO3

 

(ii) Dil. HCl reacts with thiosulphate to produce sulphur dioxide, and yellow sulphur is precipitated.

 Na2S2O3 + 2HCl 2NaCl + H2O + SO2 + S  

 

(iii) When dilute hydrochloric acid is added to copper carbonate, it decomposes to give copper chloride.

 CuCO3 + 2HCl CuCl2 + H2O + CO2 

Solution 2017-1

Dilute hydrochloric acid decomposes iron(II) sulphide to produce iron(II) chloride and hydrogen sulphide having rotten egg smell.

FeS + 2HCl FeCl2 + H2S

Solution 2017-2

Sulphuric acid precipitates the insoluble sulphate from lead nitrate solution.

Lead nitrate reacts with hydrochloric acid to give a white ppt. of lead chloride.
