f) i) Identify white solid: I R: BaSO_4 II S: Al(OH)_3 f) ii) Write the formula of the complex ion in solution T: [Al(OH)_4]^- d) To prepare a pure sample of lead(II) carbonate from lead(II) oxide: Step 1: React lead(II) oxide (PbO) with dilute nitric acid (HNO_3) to form soluble lead(II) nitrate (Pb(NO_3)_2). PbO(s) + 2HNO_3(aq) Pb(NO_3)_2(aq) + H_2O(l) Step 2: Add a solution of a soluble carbonate, such as sodium carbonate (Na_2CO_3), to the lead(II) nitrate solution. This will precipitate insoluble lead(II) carbonate (PbCO_3). Pb(NO_3)_2(aq) + Na_2CO_3(aq) PbCO_3(s) + 2NaNO_3(aq) Step 3: Filter the mixture to separate the solid lead(II) carbonate precipitate from the solution. Step 4: Wash the precipitate thoroughly with distilled water to remove any soluble impurities (
