Webb1 dec. 1979 · In an investigation, made by Herger3' 4, it has been shown, that the spe- cific resistance of a mixture of good-conducting lead dioxide (/3-PbO2) powder and insulating red lead (Pb3 O4) powder depends very steeply on the composition of the mixture. At about 70 volume percent red lead, the resistance increases steeply for a few decades. WebbLead (IV) oxide, commonly known as lead dioxide, is the inorganic compound with the formula PbO 2. It is an oxide where lead is in an oxidation state of +4. [1] It is a dark-brown solid which is insoluble in water. [2] It exists in two crystalline forms. opus international warwick

Webb, PbO2 is +4 and -4 (multiply O by 2), but on the product side, PbSO4 is +2 and -2. Is the reason that we don't multiply O on the product side by 4 is that SO4 -2 is an ion and so it stays -2, (I guess 2- because it is an oxidation state we're talking about, not a charge). So to do Redox reactions, I really need to know my ions, don't I? • WebbAtomic Mass: 15.9994 # of Atoms: 2 Mass Percent: 43.368%.
