(iv) Explain why it is not collected over water. (ii) Name the compound normally used as a drying agent during the process. (i) Explain why ammonium nitrate is not used in the preparation of ammonia. Question 3: The following questions are based on the preparation of ammonia gas in the laboratory : (ii) Nitrogen one part, hydrogen three parts. (v) Ammonia can act as a reducing agent - write a relevant equation for such a reaction. (iv) Give the equation for the manufacture of ammonia. (ii) In what ratio must the reactants be taken ? Question 2: The questions below are related to the manufacture of ammonia. Laboratory bench reagent is a diluted solution of liquor ammonia. Liquid ammonia is liquified ammonia and is available in cylinders. Liquid ammonia is used as a refrigerant because its heat of vaporisation is 5700 calories per gram molecule.
This is liquid ammonia which when further cooled freezes to a white crystalline snow like solid, which melts at – 77.7☌. When cooled under pressure, ammonia condenses to a colourless liquid which boils at – 33.4☌. When ammoniacal liquor is boiled with milk of lime, the ammonia formed is passed into ice or cold water to form liquor ammonia. Ammonia can be obtained from it by boiling. Question 1: How liquor ammonia is different from liquid ammonia ?Īnswer: A very strong solution of ammonia in water is called liquor ammonia.
