The gas evolved when dilute tetraoxosulphate (VI) acid reacts with sodium hydrogen trioxocarbonate (IV) is
- hydrogen
- oxygen
-
carbon (IV) oxide
- sulphur (VI) oxide
The correct answer is: C
Explanation
Whenever Acids react with carbonate salts to produce carbon(iv) oxide (CO2), water, and a salt:
Acid + carbonate → salt + water + carbon(iv) oxide.
In other words whenever ac acid reacts with a carbonate salt, CO2 gas is always given off or liberated. The correct answer is option C
