Lead reaction with iodide
Web27 jun. 2024 · 1 Answer. First, the iodide precipitates with lead ions, P b X +, called cations because of the positive charge. It doesn't matter what the anions are in solution, whether nitrate, acetate or other, so there's no need to add nitrates or nitric acid for this test. Second, yes, this is a test for lead in solution, but it is not at all sensitive.
