You could do the carbonate test. Only Na2CO3 will show it.

owh.... ok.. i will try it.. thank u very much!!!

anonymous · Answer

if i test it with AgNO3?

anonymous · Answer

Then NaBr will show the reaction , the product will be AgBr. But Na2CO3 donot give this reaction

I don't know much AgNO3 you have laying around, it's not cheap stuff.

$Na_2CO_3$ is the conjugate base of $H_2CO_3$, so you can titrate some cheap acid, like acetic acid. (this will require a pH meter or an indicator/litmus paper).

NaBr is just a salt, and it wont do much if you mix it with acetic acid.
