Question

To which substance is dilute sulfuric acid added to prepare lead(II) sulfate?

Answer 1

Any soluble lead(II) salt.........

Explanation:

So `"solution A"` is the obvious choice.

And we could write the reaction as....................:

`Pb(NO_3)_2(aq) + H_2SO_4(aq) rarr PbSO_4(s)darr+ 2HNO_3(aq)`

This is a very poor multiple choice question (most multiple choice questions are!), because I am willing to bet that sulfuric acid added to lead carbonate would decompose the carbonate, bring the salt briefly up into solution, and then the insoluble lead sulfate would precipitate:

`PbCO_3(s) + H_2SO_4(aq) rarr PbSO_4(s)darr+CO_2(g)uarr +H_2O(l)`

The oxide is possibly too insoluble. I might do this reaction tomorrow to see if I am right.
