Final answer:
Acids stronger than carbonic acid react with carbonate or bicarbonate ion to produce carbon dioxide gas.
Step-by-step explanation:
Any acid stronger than carbonic acid will react with carbonate or bicarbonate ion to give carbon dioxide. When an acid reacts with a carbonate or bicarbonate ion, it produces carbon dioxide gas as a product. This can be seen in the equation:
Acid + Carbonate/Bicarbonate Ion → Carbon Dioxide + Other products
For example, when sulfuric acid reacts with sodium bicarbonate, it produces carbon dioxide gas:
H2SO4 + 2NaHCO3 → Na2SO4 + 2H2O + 2CO2
