Predict the reaction, if any, that would occur if Sr(NO3)2 and Na2CO3 were mixed. Would any reaction occur if HBr were added?
Dry Sr(NO3)2 and dry Na2CO3 will not react. If aqueous solutions, yes.
Sr(NO3)2(aq) + Na2CO3(aq) ==> SrCO3(aq) + 2NaNO3(aq)
If HBr is added, carbonate reacts with H^+ to produce H2O(aq) and CO2(g)
