Which gas is produced when acids react with carbonates?
A heaped spatulaful of magnesium carbonate was
placed in a boiling tube and clamped. The end of
the delivery tube was placed in a test tube
of lime water as shown in the diagram opposite.
10 cm3 of sulphuric acid was measured and
added to the carbonate.

water
The experiment was repeated using calcium
carbonate and nitric acid.
Carbon dioxide gas was formed in this reaction. We knew this as it turned limewater
milky.
