If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. The only way the solid lead(II) iodide precipitate can form in the middle of the petri dish is for 1) the Pb(NO 3) 2 and the KI to dissociate into ions in the water and 2) the Pb 2 + ions and I-ions must migrate in the aqueous solution, i.e. Lead(II) iodide. The reaction of halides with lead nitrate is often a useful way to identify an unknown halide. Most of the lead(II) iodide precipitates out of the solution as a yellow solid (Equation 1).
