Question 94

An environmental chemist is testing water samples for heavy metal contamination.

When lead(II) nitrate solution is mixed with potassium iodide solution, a brilliant yellow precipitate of lead(II) iodide is formed, alongside a soluble solution of potassium nitrate.

Complete the word equation for this precipitation reaction.

lead(II) nitrate+....................→....................+potassium nitrate \text{lead(II) nitrate} + \text{....................} \rightarrow \text{....................} + \text{potassium nitrate} lead(II) nitrate+....................→....................+potassium nitrate
