Dilute sulfuric acid and potassium hydroxide solution are used to prepare pure, dry potassium sulfate crystals.
In a laboratory, a student first carries out a titration to find the exact reacting volumes of the acid and alkali, as shown in the diagram below:
Following the titration, a pure potassium sulfate solution is prepared, from which the dry crystals are isolated.
Describe in detail, including the names of suitable apparatus, how the student should carry out this entire experimental procedure.
