Na2CO3 + H2SO4 --> ¨
How do I solve this one?
-
:o
A base and an acid...no need to balance anything...what do you think?
-
But a reaction happens, by the way... :P
-
I was thinking something like this:
2 Na(+) + CO3(2--) + 2 H30(+) + SO4(2--) --> H2O + H2 + Na2SO4 (aq) + CO3(2--)
That can't be right, oi?

Too complicated (and not correct)! What could happen with the carbonate anion if you protonate it?
-
I thought so.
Something like this?
2 H+ + CO3-- --> H2CO3
But that's an acid too, right?
-
Correct, but H2CO3 is instable... :P
-
Wouldn't the H2SO3 decompose into CO2 and H2O?
Na2CO3 + H2SO4 ---> H2CO3 + Na2SO3 ---> H2O + CO2 + Na2SO3

H2CO3 decomposes in water and carbon dioxide, not H2SO3 :)
Na2CO3 + H2SO4 ---> H2CO3 + Na2SO3 ---> H2O + CO2 + Na2SO3
No! Sulfate is not reduced to sulfite! As you can see the oxygen atoms are not balanced.... :P

Is is too simple to suggest the following?
Na2CO3 + H2SO4 --> Na2SO4 + CO2 +H2O
a carbonate + an acid makes a salt + CO2 and water

that would be ok, but we dont know what the author of this thread is trying to find: an ionic equation, a general equation or all the reactions that occur step-by-step :P
