Given lead (ii) oxide, nitric (v) acid, sodium carbonate and water. Explain briefly how you can prepare lead (ii) carbonate. Use equations where possible.
Dissolve PbO in slight excess of HNO3, evaporate to dryness, add water and Na2CO3 to precipitate PbCO3, filter and dry.
PbO(s) + 2HNO3(aq) ==> Pb(NO3)2(aq) + H2O(l)
Pb(NO3)2(aq) +Na2CO3(s) ==> PbCO3(s) + 2NaNO3(aq)
To prepare lead (II) carbonate, the following steps can be followed:
1. Start with lead (II) oxide (PbO), nitric acid (HNO3), sodium carbonate (Na2CO3), and water (H2O).
2. First, react lead (II) oxide with nitric acid to form lead (II) nitrate and water:
PbO + 2HNO3 → Pb(NO3)2 + H2O
3. Next, react lead (II) nitrate with sodium carbonate to form lead (II) carbonate, sodium nitrate, and water:
Pb(NO3)2 + Na2CO3 → PbCO3 + 2NaNO3
4. Finally, filter the obtained solution to separate lead (II) carbonate, which is a solid precipitate, from the remaining solution.
By following these steps and using the given chemicals, you can prepare lead (II) carbonate.
