Sulphuric acid. Solution 3.<\/strong><\/span><\/p>\n (a) Anhydrous HCl is poor conductor due to the absence of ions in it whereas aqueous HCl is excellent conductor since it contains ions.<\/p>\n (b) When the stopper is opened HCl gas comes in contact with water vapors of air and gives white fumes due to the formation of hydrochloric acid.<\/p>\n (c) A solution of HCl in water gives hydronium ions and conducts electricity, but HCl is also soluble in dry toluene, but in that case it neither (i) turns blue litmus red (ii) nor does conducts electricity. This indicates the absence of H+<\/sup>\u00a0ions in toluene showing thereby that hydrogen chloride is a covalent compound.<\/p>\n (d) When ammonium hydroxide is brought near the mouth of HCl, dense white fumes are formed due to the formation of ammonium chloride. (e) Dry hydrogen chloride is not acidic whereas moist Hydrogen chloride is acidic. In presence of a drop of water HCl gas dissolves in water and forms hydrochloric acid which turns blue litmus paper red.<\/p>\n (f) Hydrogen chloride is not collected over water as it is highly soluble in water.<\/p>\n Solution 4.<\/strong><\/span><\/p>\n Difference between Hydrogen chloride gas and Hydrochloric acid is:<\/p>\n
\n(b) Phosphorous pentoxide and CaO cannot be used to dry HCl because they react with HCl.
