1. EXPERIMENTAL CHEMISTRY Filtration - lead(II) sulphate from sodium sulphate Done by: Bon Cheryl Class: 3H

3. Procedure Step 1: Prepare the lead(II) sulphate. Pour 30 cm3 of sodium sulphate into a beaker containing 50 cm3 of lead(II) nitrate solution. Stir the reaction mixture with a glass rod. Aqueous sodium sulphate Aqueous lead(II) nitrate Glass rod

4. Procedure Step 2: Fold the filter paper. Fold a piece of filter paper as shown. Place it in a filter funnel. Moisten it with a little distilled water.

5. Procedure Step 3: Filter the mixture. Pour the reaction mixture into the filter funnel that is lined with filter paper. Collect the filtrate that passes through the filter paper in a conical flask. filtrate filter paper residue reaction mixture

6. Procedure Step 4: Collect the residue The residue is lead(II) sulphate. Wash the residue with distilled water. Then dry the residue on a piece of filter paper. Distilled water Dry the lead(II) sulphate
