Short Questions<\/span><\/h3>\n

Question 1:<\/strong> (i) State one condition under which chlorine and hydrogen react to form hydrogen chloride<\/a> gas.
\n(ii) Give balanced chemical equation for the above reaction.
\n(iii) Name the gas which is a covalent compound but becomes electrovalent when dissolved in water ?
\n(iv) For which gas, ammonia fountain experiment can be used ?
\nAnswer:<\/strong> (i) Presence of diffused sunlight.
\n(ii) H2<\/sub> + Cl2<\/sub> \u00a0\u27f6 \u00a02HCl
\n(iii) Hydrogen chloride (HCl) gas.
\n(iv) Hydrogen chloride gas.<\/p>\n

Question 2:<\/strong> A colourless gas G fumes strongly in the air. The gas gives dense white fumes when a glass rod dipped in ammonia solution is held near the gas.
\nAnswer the following questions:
\n(i) Name the gas G.
\n(ii) Name two chemicals used in the preparation of the gas G.
\n(iii) Write the chemical equations for the reaction of the chemicals named in (ii) when :
\n(a) The reaction mixture is not heated.
\n(b) The reaction mixture is heated above 100\u00b0C.
\n(iv) Why does the gas G fume strongly in air ?
\n(v) Why does the gas G form dense white fumes with ammonium hydroxide ?
\nAnswer:<\/strong> (i) The gas G is hydrogen chlorine gas.
\n(ii) The chemicals are (i) sodium chloride, (ii) concentrate sulphuric acid.
\n(iii) (a) NaCl + H2<\/sub>SO4<\/sub> (conc.) \u00a0\u27f6 \u00a0NaHSO4<\/sub> + HCl (g)
\n(b) Nacl + NaHSO4<\/sub>\u00a0 \u27f6 \u00a0Na2<\/sub>SO4<\/sub> + HCl (g)
\n(iv) It is because the HCl gas is extremely soluble in water. Thus the gas dissolves in water vapour present in the air to form tiny droplets of hydrochloric acid, which appear in the form of fumes.
\n(v) The HCl gas reacts with vapours of ammonium hydroxide to form very fine solid particles of ammonium hydroxide which are white in colour. These white particles of solid ammonium hydroxide appear in the form of white fumes.<\/p>\n

Question 3:<\/strong> (i) How will you dry HCl acid<\/a> gas.
\n(ii) Give three tests of hydrogen chloride.
\n(iii) Which two colourless gases combine to form a white solid.
\nAnswer:<\/strong> (i) HCl gas can be dried by passing it over conc. H2<\/sub>SO4<\/sub>, which acts as a powerful dehydrating agent.
\n(ii) Tests for Hydrogen Chloride.
\n(1) It gives dense white fumes with a rod dipped in NH4<\/sub>OH solution.
\n(2) It produces white ppt. with AgNO3<\/sub>\u00a0solution.
\n\"ICSE
\n(3) It turns moist blue litmus red.
\n(iii) NH3<\/sub> and HCl gases combine to form a white solid NH4<\/sub>Cl
