The lead(IV) oxide used in car batteries is prepared by coat-ing the electrode plate with PbO and then oxidizing it to leaddioxide (PbO₂). Despite its name, PbO₂ has a nonstoichiometricratio of lead to oxygen of about 1/1.98. In fact, the holes in the PbO₂ crystal structure due to missing O atoms are responsiblefor the oxide’s conductivity. (a) What is the mole % of O miss-ing from the PbO₂ structure? (b) What is the molar mass of the nonstoichiometric compound?

Give reasons for the following: (i) Alumina is dissolved in cryolite for electrolysis instead of being electrolysed directly. (ii) Zinc oxide can be reduced to the metal by heating with carbon but not Cr2O3. (iii) Extraction of copper directly from sulphide ores is less favourable than that from its oxide ore through reduction.
An impure sample of Na3PO3 weighing 0.1392 g was dissolved in 25 mL of water. A solution containing 50 mL of 3% w/v mercury(II) chloride, 20 mL of 10% w/v sodium acetate, and 5 mL of glacial acetic acid was then prepared. The solution containing the phosphite was added dropwise to the second solution, oxidizing PO3^3– to PO4^3– and precipitating Hg2Cl2. After digesting, filtering, and rinsing, the precipitated Hg2Cl2 was found to weigh 0.4320 g. Report the purity of the original sample as %w/w Na3PO3. Moles Na3PO3 = moles Hg2Cl2
