What happens when you add lead carbonate to sulphuric acid?

Darren Farley  Follow

CuCO3 + H2SO4(l) = CuSO4 + H2O(l) + CO2(g)

Change in Free Energy: ΔG(20C) = -139.9kJ (negative, so the reaction runs)

Change in Enthalpy: ΔH(20C) = -27.4kJ (negative, so the reaction is exothermic)

Some people might think that:

CuCO3 + H2SO4(l) = CuSO4 + H2CO3(a)

But the carbonic acid instantly dissociates into H2O(l) and CO2(g)

Vinegar does not contain sulfuric acid. Vinegar is a natural product of fermentation and aging from many different sources, including wine. The alcohol is converted to acetic acid. You can buy many different flavors of vinegar in the supermarket. You will also see white vinegar. This is vinegar which has been distilled to remove nearly all of the colored compounds and flavor components in natural vinegar. It is mostly water and acetic acid.

PbCO3 + H2SO4 = PbSO4 + H2O + CO2

Generally 98% sulfuric acid is sold in the market so use dilution formula, say for example we wish to prepare 100 ml of 10% volume by volume solution

then

98% X ml? = 10 % X 100

X ml= 1000/98 = 10.20ml

now add 89.8ml of water in 100 ml volumetric flask then add 10.20 ml sulfuric acid into it.

Note: sulfuric is very dangerous acid if contacted, so please strictly follow lab safety measures while preparing above mentioned 10% solution.

Dear Anonymous.

Why are you posting this anonymously? Are you ashamed that you didn’t study properly and will, therefore make a complete fuck-up of your homework?

You do realize that your teacher has software to detect cheats - and that it looks on Quora for questions and answers that match your homework?

Were I in the lab, I would do the experiment …. but I assume the following reaction takes place…

[math]PbCO_{3}(s)uparrow + H_{2}SO_{4}(aq) ightarrow PbSO_{4}(s)downarrow +CO_{2}(g)uparrow + H_{2}O(l)[/math]

The lead carbonate would go up … a white salt of lead sulfate would precipitate, and carbon dioxide would be evolved… So what did you see?

Effervescence due to formation of carbon dioxide gas…and formation of lead sulphate solution and water

Lead carbonate + sulphuric acid - - - > lead sulphate + water + carbon dioxide gas

PbCO3 + H2SO4 = PbSO4 +H2O + CO2 In same way other carbonates react but excluding PbCO3, CaCO3, BaCO3, SrCO3 form insoluble sulfates but majority of sulfates are soulble
