Question 34

Transition metal salts can be synthesized by reacting an insoluble metal precursor with a suitable acid.

Plan a laboratory experiment to prepare a pure, dry sample of nickel(II) sulfate crystals, NiSO4⋅6H2O\text{NiSO}_4 \cdot 6\text{H}_2\text{O}NiSO4​⋅6H2​O, starting from an appropriate insoluble nickel(II) compound and a suitable acid.

Your plan must include:

  • the names of both starting materials
  • a step-by-step description of the practical procedure, identifying the apparatus used at each stage
  • the specific steps taken to ensure the resulting crystals are pure and dry.
