Step-by-step solution

4 steps

f) i) Identify white solid:
I R: BaSO4\boxed{\text{BaSO}_4}
II S: Al(OH)3\boxed{\text{Al(OH)}_3}

f) ii) Write the formula of the complex ion in solution T:

[Al(OH)4]−\boxed{[\text{Al(OH)}_4]^-}

d) To prepare a pure sample of lead(II) carbonate from lead(II) oxide:

  1. React lead(II) oxide (PbO\text{PbO}) with dilute nitric acid (HNO3\text{HNO}_3) to form soluble lead(II) nitrate (Pb(NO3)2\text{Pb(NO}_3)_2).

    PbO(s)+2HNO3(aq)→Pb(NO3)2(aq)+H2O(l)\text{PbO}(s) + 2\text{HNO}_3(aq) \to \text{Pb(NO}_3)_2(aq) + \text{H}_2\text{O}(l)

  2. Add a solution of a soluble carbonate, such as sodium carbonate (Na2CO3\text{Na}_2\text{CO}_3), to the lead(II) nitrate solution.

    This will precipitate insoluble lead(II) carbonate (PbCO3\text{PbCO}_3).

    Pb(NO3)2(aq)+Na2CO3(aq)→PbCO3(s)+2NaNO3(aq)\text{Pb(NO}_3)_2(aq) + \text{Na}_2\text{CO}_3(aq) \to \text{PbCO}_3(s) + 2\text{NaNO}_3(aq)

  3. Filter the mixture to separate the solid lead(II) carbonate precipitate from the solution.

  4. Wash the precipitate thoroughly with distilled water to remove any soluble impurities (
