A student added acid to a metal carbonate and passed the gas through lime water. What is the correct observation?

Answer and explanation

Correct answer: Lime water will turn milky

This experiment demonstrates the characteristic test for carbon dioxide. A metal carbonate reacts with an acid to produce a salt, water and CO₂. When the gas is bubbled through lime water, it reacts with calcium hydroxide and forms insoluble calcium carbonate, making the solution appear milky: CO₂ + Ca(OH)₂ → CaCO₃ + H₂O. The colour changes in B and C are unsupported, while D ignores gas formation. Hence A is correct.
