Experiment 1 - Gravimetric Analysis

Step 2: Precipitating the Pb2+ ion

The following tutors will guide you through the processes in step 2.

In step 2, we add a solution that will cause all of the Pb2+ in the solution to precipitate out as the insoluble salt PbSO4. Which of the following solutions should we use to form this precipitate?
Hint
Deionized Water
0.35 M sodium sulfate
2.0 M ethanoic (acetic) acid
Good Job!
That's not quite right.
Hint:
Which of the above solutions will react with Pb2+ to form an insoluble salt?
