Given lead oxide, nitric acid, sodium carbonate solution, and water, how can you prepare lead carbonate?

Add a minimum amount of nitric acid to lead oxide to fully dissolve. Swirl or stir, warm if necessary.

Then, add an excess of sodium carbonate to precipitate lead carbonate. Filter and rinse precipitate.

In the strictest technical sense, yes you can. Dilute it you must. I think household vinegar is only about 4% acetic acid. Glacial acetic acid is >98% acetic acid. But why would you need to? Laboratory grade acetic acid is so much more expensive than the vinegar you would buy in the store. Handling glacial acetic acid is not for the masses. When I’ve used glacial acetic acid back in the day it’s been under a fume hood. Take the odor of white vinegar and kick it up several orders of magnitude when you open that bottle to use it. It burns too, as most concentrated acids do.

“How can one prepare lead sulphate when given lead oxide, nitric acid, sodium sulphate, and water?”

Great, another homework question asked anonymously.

I usually don’t answer such questions, but I’m feeling generous today (call it Atheist’s Xmas Spirit, two huge contradictions in one).

Let’s go.

Step one: dissolve the lead oxide in the nitric acid, producing lead nitrate:

Step two: precipitate the lead sulfate by adding a solution of sodium sulfate to the lead nitrate you’ve just made.

Now, don’t be a lazy anonymous and search the equations for the reactions I told you.

People are making this way too complicated. Sodium carbonate molecular formula is Na2CO3. No protons in the compound so the possibility of being an acid are pretty much zero. Could be just a salt without acidic or basic properties. But, it isn’t. The anion is carbonate and, in water does the following:

CO3(2-) + H2O = HCO3- + OH-

So, put sodium carbonate in water and you will generate hydroxide (OH-) and the solution will become alkaline.

Look up the solubility of lead oxide in water, acid, base. If it dissolves in acid, do so (carefully nitric acid is very corrosive and solvated lead is very toxic). Look up the solubility of lead carbonate in acid, water and base. Sodium carbonate is a moderate base. Adjust the sodium carbonate solution to the most insoluble pH for lead carbonate using the nitric acid if necessary. Add the lead nitrate to the pH adjusted sodium carbonate. Filter, rinse, and dry the precipitate.

Don’t add sodium carbonate to the lead nitrate. You don’t want CO[math]_2[/math] bubbling off and spreading dangerous lead compounds.

Well, we could write the stoichiometric equation that represents the reaction of calcium carbonate with nitric acid…and thus…

[math]CaCO_{3}(s) + 2HNO_{3}(aq) longrightarrow Ca(NO_{3})_{2}(aq) + CO_{2}(g)uparrow + H_{2}O(l)[/math]

And thus ONE equiv of carbonate reacts with 2 equiv of acid to give 1 equiv of calcium nitrate salt, 1 equiv of water, and 1 equiv of carbon dioxide gas….

But you have provided NO details as to the masses, volumes, or concentrations of the starting reagents…so we are shot birds..

Through the following steps, we can prepare lead carbonate ( PbCO3):

• PbO + 2HNO3 → Pb( NO3)2 + H2O

• Pb( NO3)2 + Na2CO3 → PbCO3 + 2NaNO3.

Na2CO3 is a basic salt formed by the reaction between H2CO3 (Carbonic acid) and Sodium hydroxide (NaOH).

H2CO3 +2 NaOH →Na2CO3 +2H2O

Since Carbonic acid is a weak acid and caustic soda is a strong base, therefore the salt formed by their reaction is a basic salt

Dissolve ZnO in HNO3. You get a Zn(NO3)2 solution. Then add Na2CO3 in to it . There you get Zn(CO3)2 liquid.Don't put Na2CO3 &HNO3 together because CO2 releases by that.
