Answer:
By passing the gas through lime water
Explanation:
The equation of the reaction of vinegar with calcium carbonate in the form of marble chips is shown below;
CaCO3(s) + 2CH3COOH(aq) ---------> Ca(CH3COO)2(aq) + H2O(l) + CO2(g).
We can see from the reaction equation that the gas produced is carbon dioxide. This gas is identified by passing the gas through lime water. If lime water turns milky, then the gas is truly carbon dioxide.
