Given below is the industrial process for the manufacture of ammonia gas. Study the schematic diagram to answer the following questions.
(a) Name the process.
(b) Which catalyst is used in the above process?
(c) In the above diagrammatic setup, how is ammonia gas separated from the unreacted gases to obtain liquid ammonia?
(d) Which two properties of ammonia gas can be demonstrated by the Fountain Experiment?

(a) Haber's process.
(b) Finely divided iron.
(c) The mixture of ammonia and unreacted gases (N2 and H2) coming out of the catalytic chamber is passed through the cooling pipes (condenser). Ammonia liquefies first, whereas nitrogen and hydrogen do not liquefy easily. The ammonia produced is stored as liquid under pressure.
(d) The two properties of ammonia gas demonstrated by the Fountain Experiment are:
- Ammonia gas is highly soluble in water.
- Ammonia is a basic gas (its aqueous solution turns red litmus blue / phenolphthalein turns pink).
