Question

what is the chemical equation for testing the presence of carbon dioxide in the air??

Answer 1

Answer:

Carbon dioxide reacts with calcium hydroxide solution to produce a white precipitate of calcium carbonate. Limewater is a solution of calcium hydroxide. If carbon dioxide is bubbled through limewater, the limewater turns milky or cloudy white.

Answer 2

Answer:

You can test the presence of carbon oxide passing the air into lime water.

• If lime water turns milky, it means that air contains carbon dioxide.
• If lime water does not turn milky, it mean that air doesn't contain carbon dioxide.

Here's the chemical reaction between carbon dioxide and lime water:

CO₂ + Ca(OH)₂ => CaCO₃ + H₂O

(Carbon Dioxide) (Limewater) (Calcium Carbonate) (Water)
