WebWhy does Pb exist as an ion with +2 valance? The preference of P b for the lower oxidation state is an example for the so-called inert pair effect. Due to relativistic contraction of the outermost s orbital, its 2 electrons are closer to the nucleus and thus more tightly bound than the electrons in the p orbitals.

WebAn ion imprinted polymer (IIP) was synthesized by using Pb(II) as a template, methacrylic acid as a monomer, 8-hydoxyquinoline as a ligand, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, and azobisisobutyronitrile as initiator. It can be applied to prepare lead ion selective voltammetric sensor for Pb(II) adsorption and trace detection. WebTechniques for identifying the presence of the Pb 2+ ion in water generally rely on the precipitation of lead (II) chloride using dilute hydrochloric acid. As the chloride salt is sparingly soluble in water, in very dilute solutions the precipitation of lead (II) sulfide is instead achieved by bubbling hydrogen sulfide through the solution. [65]
