Write balance chemical equation
Carbon dioxide gas is passed through lime water to form a precipitate of calcium carbonate

Open in App

Solution

ime water is calcium hydroxide (Ca(OH)₂. When carbon dioxide is passed into it, it turns milky because of the formation of calcium carbonate (CaCO₃). The balanced reaction is as follows:

Ca(OH)₂ + CO₂→ CaCO₃ + H₂O
