Detailed information about the equation
Reaction conditions when applied H2O + CO2
- Catalyst: not available
- Temperature: normal
- Pressure: normal
- Other conditions: not available
Reaction process H2O + CO2
Process: Place a litmus and water into the test tube, then carry out an aeration of CO2, and heat the solution
Note: CO2 reacts with water to create acid solution, turning litmus into red. H2CO3 is not stable, easy to be decomposed into CO2 and H2O. After heating, the solution wil turn red litmus into violet.
The result of the reaction H2O + CO2
The phenomenon: Litmus papar turns red. After being heated, it turns violet.
