Sodium carbonate solution is basic and gives a gas with acid. How will this gas be identified?

Answer and explanation

Correct answer: It will turn lime water milky

Sodium carbonate reacts with an acid to release carbon dioxide: Na₂CO₃ + 2HCl → 2NaCl + H₂O + CO₂. Carbon dioxide is identified by passing it through limewater, where it reacts with calcium hydroxide to form insoluble calcium carbonate, making the limewater milky. A pop sound is the test for hydrogen, not carbon dioxide. Litmus and turmeric describe general acid-base behaviour and are not the specific gas test required here.
