BaCO3 is already an insoluble salt

sorry..is become soluble salt

the answer is what ?
from what I understand, that question is asking which one can dissolve BaCO3

As I remember, only acid is able to remove carbonate salts.

but u see this..BaCO3 + H2SO4 --> BaSO4 + CO2 + H2O.....

BaSO4 is insoluble salt wor

Added on November 8, 2008, 10:32 pmmean that which one can react with BaCO3 to produce an soluble salt izzit?

Add sodium chloride which will cause a displacement reaction.
BaCO3+2NaCl-->BaCl2+Na2CO3

that's why I said, the question is asking you about which one can dissolve BaCO3 and it doesn't necessary the product be in soluble state.
my opinion lah

BaSO4 is insoluble in water but it is soluble in acid, right??

so u would say D because the product formed is soluble?

good luck for all of you!!!!

SPM is not that hard actually and i managed to get it with flying colours ^^

dun be panic and you can excel on it. good luck again

Displacement ? I think that happens only when add in reactive metal to a solution.

Your equation is more to double decomposition and it only happens between two soluble salts

Depends on what kind of acid.In HCl and HNO3 yes, cause it will cause a displacement reaction but not in H2SO4

Its not really double decomposition since both of the salts produced are soluble.

be confidence

so how?? dun confuse me pls

From what i noe displacement must add in a more electropositive metal..
Like a zinc metal..It cant be in solution..

answer is what leh ?

book and is D..but how to get de?

agree

Ok, don't know what the reaction for that is called, but it will react.
