You should add few drops of dilute acid such as HCL or H2SO4 to the salt.
Once the process is completed, colorless gas escapes in the form of product and displays brisk effervescence.
When you are passing the gas through lime water, it turns milky within a very short period of time.
The gas is C02 and the salt is regarded as the carbonate of the metal.
