When we test for carbon dioxide gas, we bubble it through limewater and get a white precipitate CaCO3. What is the equation for the reaction?
Is it
CO2 + Ca(OH)2 --> CaCO3 + H2O
Answered by DrBob222
Yes, and the equation is balanced. You can dress it up a little by adding the phase as follows:
CO2(g) + Ca(OH)2(aq) ==> CaCO3(s) + H2O(l)
