Lead (II) iodide is a toxic, yellowish self-colored. It presentations a compass of colors in with varying temperature from bright yellow at way temperature to brick red. On cooling, its color returns to yellow. Fashionable thems lucid form it equals practised as a sensing element corporeal for heights energy photons including roentgenograms and gamma beams of light.
Because of the insolubility of therefore a few lead(II) combines, the accustomed source of confidential information(II) ions fashionable solution is lead(II) nitrate solution - and that will be assumed in completely the following examples.
Lead(II) chloride can be made as a white precipitate by adding together a resolution bearing chloride ions to lead(II) nitrate solution. You could use things like atomic number 11 chloride resolution to provide the chloride ions, but it is usually easier just to add some dilute hydrochloric acid.
Adding a source of aqueous sulphate ions to a resolution of conduct(II) nitrate results in a white precipitate of lead(II) sulphate. The easiest thing to attention deficit hyperactivity disorder is ordinarily diluted sulphuric back breaker - only whatsoever other dissoluble sulphate would do.
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.
