Question

How do you test for the presence of co2

Answer 1

Please mark as brainliest

The most effective way to test for CO2 is to bubble the gas through "limewater", a diluted solution of calcium hydroxide (slaked lime). When you bubble carbon dioxide through the solution, it forms a solid precipitate of calcium carbonate – chalk or limestone.

By passing the gas to lime water it will turn it as milky by that you can identify that as CO2

⚫️Ca(OH)2 + CO2 ———->CaCO3 +H2O
