How will you be able to tell whether the gas used in the experiment was hydrogen chloride or ammonia. You enter a laboratory after a class has completed the Fountain Experiment. Give equation for – reaction in which NH 3 is oxidized by : Write a balanced equation for the following reaction :Īmmonium sulphate from ammonia and dilute sulphuric acid. Use of a catalyst : Iron (Fe) and use of a promotor : Molybdenum (Mo).With reference to Haber’s process for the preparation of ammonia, write the equation and the conditions required. Write a balanced chemical equation to illustrate the reducing nature of ammonia.
Name the substance used for drying ammonia, State what is observed when excess of ammonia is passed through an aq. The compound is not a metal hydroxide, its aqueous solution is alkaline in nature.įrom the list of substances given - Ammonium sulphate, Lead carbonate, Chlorine, Copper nitrate, Ferrous sulphate - State :Ī compound which on heating with sodium hydroxide produces a gas which forms dense white fumes with hydrogen chloride.
Select the correct compound from the list given - Ammonia, Copper oxide, Copper sulphate, Hydrogen chloride, Hydrogen sulphide, Lead bromide - which matches the description given below : A mixture of ammonium chloride and slaked lime is heated.Write the equations for the following reactions which result in the formation of ammonia. Hydroxyl ion (NH 3 + H 2O → NH + 4 + OH – ) Name the ion other than ammonium ion formed when ammonia dissolves in water. Write an equation for the reaction of chlorine with excess of ammonia. State the purpose of liquefying the ammonia produced in the process.īy liquefying ammonia, it can be easily seperated from unreacted N 2 and H 2 gases. Write the equation for the reaction in the Haber’s process that forms ammonia. This gas burns in oxygen with a green flame.When this gas is bubbled through copper sulphate soln., a deep blue coloured solution is formed.Which compound is normally used as a drying agent for ammonia.įrom the gases ammonia, hydrogen chloride, hydrogen sulphide, sulphur dioxide – Select the following : Why is ammonia not collected over water.Īmmonia gas is lighter than air and hence collected by the downward displacement of air.Īmmonia is not collected over water because it is highly soluble in water. Write the equation for the formation of ammonia by the action of water on mangesium nitride. How would you distinguish between Zn 2+ and Pb 2+ using ammonium hydroxide solution. Name a gas whose solution in water is alkaline. Write the equation for the reaction – when the gas is passed over heated CuO. What are the products formed when ammonia is oxidized with copper oxide.įrom the following gases – ammonia, chlorine, hydrogen chloride, sulphur dioxide, select the gas that turns moist red litmus paper blue. Write the equation for the preparation of NH3 from ammonium chloride and calcium hydroxide.ĢNH 4Cl + Ca(OH) 2 → CaCl 2 + 2NH 3 + 2H 2O Warming ammonium sulphate with sodium hydroxide solution. Name (formula is not acceptable) the gas produced in the following reaction : Neutral litmus solution is added to an alkaline solution.
