A student set up the apparatus as shown in the diagram below to prepare and collect dry
Ammonia gas

i) Identify two mistakes in the set up and give a reason for each mistake.
ii) Name a suitable drying agent for ammonia.
iii) Describe one chemical test for ammonia gas

---

i)I. Mistake: Ammonia is being collected using the wrong method

reason: Ammonia is less dense than air hence cannot be collected by downwards delivery

II. Mistake: The flask is not slanted

Reason: Condensed water will flow back to the hot flask making it crack.

ii) Calcium oxide

iii) When moist red litmus paper is put in ammonia gas it turns blue.
