how can u get a carbonate ion from the three salts that u wrote under salt analysis????

 

[ritmraz]

CO2 liberated by dilute acids. u will see the bubble (which means the gas) in the test tube when u add some H2SO4 to carbonate ion

 

[lushpush]

well i know that! but there is no carbonate ion in the three salts that masterboss mentioned????? cant u see that????
