Given sodium carbonate solid ,lead II nitrate solid and water explain how you can obtain a solid sample of lead II carbonate
Na2CO3 + Pb(NO3)2 ==> PbCO3 + 2NaNO3
Both Na2CO3 and Pb(NO3)2 are soluble in water. Add water to the two solids, lead(II) carbonate will precipitate, filter, the solid will stay behind in the filter filter, the liquid will go through into the collection jar. Wash the ppt with extra water. let the ppt dry and you have made PbCO3 (lead II carbonate)
To obtain a solid sample of lead II carbonate, you can use the reaction between sodium carbonate (Na2CO3) and lead II nitrate (Pb(NO3)2) to form lead II carbonate (PbCO3).
Here are the steps to follow:
1. Measure and weigh the required amounts of sodium carbonate (Na2CO3) and lead II nitrate (Pb(NO3)2) solids. The molar ratio between the two compounds is 1:1, so you need an equal number of moles of each.
2. Dissolve the sodium carbonate (Na2CO3) in a small amount of distilled water. Stir the solution thoroughly until all the solid has dissolved.
3. In a separate container, dissolve the lead II nitrate (Pb(NO3)2) in another small amount of distilled water. Again, stir until all the solid has dissolved.
4. Slowly pour the lead II nitrate solution into the sodium carbonate solution while continuously stirring. A white precipitate of lead II carbonate (PbCO3) should form immediately.
5. Allow the mixture to sit undisturbed for some time to ensure complete precipitation. The lead II carbonate will settle at the bottom of the container as a solid.
6. Carefully pour off the liquid (the supernatant) from the container, leaving behind the solid lead II carbonate. Try to avoid disturbing the solid during this process.
7. Lastly, wash the solid lead II carbonate with a small amount of distilled water to remove any impurities or remaining soluble substances. Allow the solid to dry thoroughly, either by air drying or using a mild source of heat like an oven.
By following these steps, you should obtain a solid sample of lead II carbonate. Make sure to handle chemicals safely and dispose of any waste properly, following appropriate guidelines.
To obtain a solid sample of lead(II) carbonate, you can follow the steps below:
Step 1: Set up a reaction vessel
Begin by setting up a clean reaction vessel or beaker for the reaction. Make sure it is large enough to accommodate the chemicals and allow for stirring.
Step 2: Measure and add sodium carbonate
Weigh a known amount of sodium carbonate solid. Sodium carbonate is commonly available as a white powder. Add the measured amount of sodium carbonate to the reaction vessel.
Step 3: Measure and add lead(II) nitrate
Similarly, measure an equimolar amount of lead(II) nitrate solid. Lead(II) nitrate usually appears as a white crystalline solid. Add the measured lead(II) nitrate to the same reaction vessel containing the sodium carbonate.
Step 4: Add water
Measure a sufficient amount of water to dissolve the reactants and create a solution. Slowly add the water to the reaction vessel, a little at a time, while stirring continuously with a glass rod. Keep adding the water until the solids are fully dissolved.
Step 5: Observe the formation of lead(II) carbonate
As you add water and stir the solution, you will notice a white precipitate forming. This precipitate is lead(II) carbonate. It will appear as a fine white powder suspended in the liquid.
Step 6: Allow the solution to settle
Once the precipitate has formed, allow the solution to sit undisturbed for some time. This will allow the lead(II) carbonate to settle at the bottom of the reaction vessel.
Step 7: Decant the liquid
Once the lead(II) carbonate has settled, carefully pour off the liquid portion. This process is called decanting. Pour the liquid into a separate container, being careful not to disturb the settled solid at the bottom.
Step 8: Collect the solid lead(II) carbonate
After decanting the liquid, you will be left with solid lead(II) carbonate at the bottom of the reaction vessel. Use a filter or a funnel lined with filter paper to collect the solid. Pour the remaining solution through the filter, leaving behind the lead(II) carbonate on the filter paper.
Step 9: Rinse and dry the solid
After collecting the solid lead(II) carbonate, rinse it with a small amount of distilled water to remove any remaining impurities. Carefully transfer the solid to a clean, dry beaker or watch glass. Allow the lead(II) carbonate to dry completely, either by air-drying or using an appropriate heating method.
Following these steps, you will obtain a solid sample of lead(II) carbonate.
