MrLundScience | Lead II Nitrate Reaction With Potassium Iodide - Pb(NO3)2 + KI @MrLundScience | Uploaded July 2019 | Updated October 2024, 4 days ago.
Dissolved iodide ions, when in the presence of dissolved lead II ions, will produce the vibrant yellow insoluble solid, lead II iodide. In this double displacement precipitation reaction, lead II nitrate solution is added to potassium iodide solution. Iodide treatment of water can be used as an indicative test for the presence of the lead II ion.
