Question 24

Ammonia solution and dilute nitric acid are used to prepare pure, dry ammonium nitrate crystals.

In an experiment, a titration is carried out to determine the exact volumes of ammonia solution and dilute nitric acid that react together.

Then, an ammonium nitrate solution is prepared from which the pure, dry crystals are obtained.

Describe in detail, using suitable apparatus, how this experiment should be carried out.
