Specification Point 2.43C (Paper 2C Only):
Practical: Prepare a sample of pure, dry Lead (II) Sulfate
Preparation Of Pure, Dry Lead (II) Sulfate Crystals
The filtration of the mixture to remove the precipitate
Soluble Salt 1 = Lead (II) Nitrate Soluble Salt 2 = Potassium Sulfate
- Dissolve Lead (II) Nitrate and Potassium Sulfate in water and mix together using a stirring rod in a beaker
- Filter to remove precipitate from mixture
- Wash filtrate with water to remove traces of potassium nitrate solution
- Leave in an oven to dry
Equation of Reaction:
|Lead (II) Nitrate + Potassium Sulfate → Lead (II) Sulfate + Potassium Nitrate |
Pb(NO3)2 (s) K2SO4 (s) PbSO4 (s) KNO3 (s)
