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.

According to NASA, the solar eclipses in March will be a total eclipse, as will the August 2017 eclipse. The September 2016 and February 2017 eclipses will both be annular eclipses, which means a ring of sunlight will remain visible.
