How could you test carbon dioxide and water in combustion?

Answer 1

Bubble smoke into limewater,if it turns to milky color and become colorless when bubbling continue.It proves that CO2 present Send smoke through anhydrous CuSO4,if white color turns blue water is present

Answer 2

To test for carbon dioxide (CO2), you can use lime water. Bubble the gas being tested through lime water, and if it turns cloudy or milky, that indicates the presence of CO2. To test for water (H2O), you can use a drying agent like anhydrous copper sulfate. If the drying agent changes color from white to blue, it means water is present.
