Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O.PbO occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure. In lead (IV) oxide, lead (Pb) has a valence +4 and the valence of oxygen (O) is -2. To get a neutral compound, we only need one cation and two anions, i.e. {eq}1(+4)+2(-2)=0 {/eq} . Lead(IV) oxide is the inorganic compound with the formula PbO 2. It is an oxide where lead is in an oxidation state of +4. It is a dark-brown solid which is insoluble in water. It exists in two crystalline forms. It has several important applications in electrochemistry, in particular as the positive plate of lead acid batteries
Ionic bonds are atomic bonds created by the attraction of two differently charged ions.The bond is typically between a metal and a non-metal. The structure of the bond is rigid, strong and often crystalline and solid. View Lead Reacts With Oxygen To Give Lead (IV) Oxide.pdf from PHYS 1704 at Fordham University. 012345678 9 \u000E\u000F

In the case of lead(IV) oxide, the reaction has to be done with ice-cold hydrochloric acid. If the reaction is done any warmer, the lead(IV) chloride decomposes to give lead(II) chloride and chlorine gas. This is an effect of the preferred oxidation state of lead being +2 rather than +4.Jan 01, 1984 · Lead(IV) oxide electrodes are shown to give near-theoretical calibration slopes for lead(II) ions over the range 10 −3 –10 −5 mol l −1, and to have near-theoretical standard potentials in different acidic media. They are compared with lead sulphide-silver sulphide membrane electrodes and shown to be more tolerant of acidity and copper(II), mercury(II) and iron(III) ions.
