The yellow solid known as lead(II) iodide has a melting point of 402 °C and is insoluble in water.

What is the underlying mechanism of the reaction between potassium iodide and lead(II) nitrate?

A double displacement reaction in which the positive ions of the reactants swap places to form new compounds is the mechanism of the reaction between lead(II) nitrate and potassium iodide. The nitrate anion (NO3-) combines with the potassium cation (K+) to produce potassium nitrate, whereas the lead(II) cation (Pb2+) combines with the iodide anion (I-) to produce lead(II) iodide.

What kinds of things can lead(II) iodide be used for?

Lead(II) iodide has a number of uses in electronics, nuclear radiation detection, and photography. It is utilized as a scintillation material in nuclear radiation detectors and as a photographic emulsion in X-ray film. Additionally, it is utilized as a semiconductor material in solar cells and photodiodes.

How can lead(II) nitrate be harmful?

Lead(II) nitrate is poisonous on the grounds that it contains lead, which is a weighty metal that can collect in the body and hurt the sensory system, kidneys, and different organs. Children who are exposed to lead may experience developmental delays, behavioral issues, and a lower IQ. Lead(II) nitrate should be handled with care and disposed of appropriately because lead poisoning is a serious health risk.
