given lead(ii)oxide,nitric acid,sodium carbonate and water,explain how you can prepare lead carbonate
I need an answer
water is used to make solutions of acid
HNO3(aq)+PbO(i)>Pb(NO3)2(aq) +H2O(l)
Pb(NO3)2(aq)+Na2CO3(aq)>PbCO3(s) + H2O
I need anser
So helpful...I liked the balancing
It was good
To prepare lead carbonate using lead(II) oxide, nitric acid, sodium carbonate, and water, follow these steps:
1. Start by preparing a dilute solution of nitric acid. Nitric acid is commonly available in concentrated form, so you need to dilute it. Add a specific volume of concentrated nitric acid to an appropriate volume of water, while slowly pouring the acid into water with constant stirring. Remember to always add acid to water, not the other way around, to prevent splashing and potential hazards.
2. Dissolve the lead(II) oxide (PbO) in the dilute nitric acid. This will result in the formation of lead(II) nitrate (Pb(NO3)2) and water. Stir the mixture until the lead(II) oxide is completely dissolved.
PbO + 2HNO3 → Pb(NO3)2 + H2O
3. Now, prepare a solution of sodium carbonate (Na2CO3). Sodium carbonate is available as a solid, so measure the required amount and dissolve it in water. Stir the solution until all the sodium carbonate is completely dissolved.
4. Slowly add the sodium carbonate solution to the lead(II) nitrate solution while stirring. A reaction will occur between the lead(II) nitrate and sodium carbonate to produce lead carbonate (PbCO3), sodium nitrate (NaNO3), and water.
Pb(NO3)2 + Na2CO3 → PbCO3 + 2NaNO3
5. Continue stirring the mixture until the lead carbonate precipitates out of the solution. The lead carbonate will appear as a white solid.
6. Allow the mixture to settle, allowing the lead carbonate to fully separate from the solution. You may also use filtration to separate the precipitate from the remaining liquid.
7. Wash the obtained lead carbonate precipitate with water to remove any impurities or excess reactants. This can be done by adding water to the precipitate, stirring, and then filtering or decanting the mixture.
8. Finally, dry the lead carbonate precipitate. This can be achieved by spreading the wet precipitate on a filter paper or evaporating the water off in a controlled environment, such as an oven, until the solid becomes dry.
That's it! You have successfully prepared lead carbonate using lead(II) oxide, nitric acid, sodium carbonate, and water.
