Preparation of LeadII Sulfate Using Potassium Sulfate, LeadII Carbonate, and Nitric Acid

Introduction

The process of synthesizing LeadII Sulfate (PbSO4) from solid Potassium Sulfate (K2SO4), solid LeadII Carbonate (PbCO3), and dilute Nitric Acid (HNO3) is a fascinating example of chemical reactions and precipitations. This method not only provides a clear understanding of the underlying chemical principles but also offers practical applications in various industries.

Materials Needed

Potassium Sulfate (K2SO4) Potassium Sulfate (K2SO4) LeadII Carbonate (PbCO3) Dilute Nitric Acid (HNO3) Distilled Water Beakers (2) Syringe or Pipette Stirring Rod Filter Paper Funnel

Procedure

Dissolving Potassium Sulfate

Dissolve a measured amount of solid potassium sulfate (K2SO4) in distilled water in a beaker to prepare a potassium sulfate solution.

Preparing LeadII Nitrate Solution

In a separate beaker, add solid leadII carbonate (PbCO3) to dilute nitric acid (HNO3). The reaction will produce leadII nitrate (Pb(NO3)2), carbon dioxide (CO2), and water (H2O). Chemical Reaction: PbCO3(s) 2HNO3(aq) → Pb(NO3)2(aq) CO2(g) H2O(l) Stir the mixture until all the leadII carbonate reacts and dissolves, producing a clear solution of leadII nitrate.

Mixing Solutions

Slowly add the potassium sulfate solution to the leadII nitrate solution while stirring. This will result in the formation of leadII sulfate (PbSO4), which is insoluble in water, and potassium nitrate (KNO3), which remains in solution. Chemical Reaction: Pb(NO3)2(aq) K2SO4(aq) → PbSO4(s) 2KNO3(aq) As you mix the solutions, a white precipitate of leadII sulfate will form.

Filtration

Use filter paper and a funnel to filter the mixture. Collect the white precipitate of leadII sulfate on the filter paper.

Washing the Precipitate

Rinse the precipitate with distilled water to remove any adhering potassium nitrate solution.

Drying

Allow the leadII sulfate precipitate to dry completely before using or storing it.

Summary

By following these steps, you will successfully prepare LeadII Sulfate from potassium sulfate, leadII carbonate, and dilute nitric acid. It is essential to handle all chemicals with care and follow appropriate safety protocols, including wearing gloves and goggles.
