Making lead(II) sulphate Adding a source of aqueous sulphate ions to a solution of lead(II) nitrate results in a white precipitate of lead(II) sulphate. The easiest thing to add is usually dilute sulphuric acid-but any other soluble sulphate would do.Making lead(II) iodide. If you add colourless potassium iodide solution (or any other source of iodide ions in solution) to a solution of lead(II) nitrate, a bright yellow precipitate of lead(II) iodide is produced.he easiest thing to add is usually dilute sulphuric acid-but any other soluble sulphate would do.
