Question 8
FA student made a sample of ammonium sulfate in the laboratory. The student added dilute sulfuric acid from the apparatus labelled A in Figure to 25 cm3 of ammonia solution until the ammonia solution was exactly neutralised. The student then made a pure, dry sample of ammonium sulfate crystals from the solution.

a.[1]
Name the salt made when ammonia solution reacts with dilute sulfuric acid.
b.[1]
Use Figure to name the apparatus labelled A.
c.[2]
Describe how the student made a pure, dry sample of ammonium sulfate crystals from the neutralised solution.
d.[1]
Give one difference between this laboratory preparation of ammonium sulfate and the industrial production of ammonium sulfate.
