well let's concentrate on the first query
H
2SO
4 + H
20 -> HSO
4- + H
30
+Then
HSO
4- + H
2O <-> SO
42- + H
30
+But here Ka
2= 10
-2 do the approximations work here?
If not (i think they don't) how will i get C? too complicated
As for the other I think it's:
H
2SO
4 + NaOH -> Na
2SO
4 + H
20
And here i have other queries which i am going to say after we finish the first question...
