First CO2 plus Ca2+ plus 2OH - to produce CaCO3 precipitation and water
Then CaCO3 plus H2O plus CO2 produces Ca2+ and 2HCO3-
But I don't know the general reaction equation. I' m sorry! I guess "the answer is wrong ", should be due to the formation of CaCO2 precipitation in the middle!

What is the ionic equation for laboratory testing co2 gas with clear lime water? If excess co2 is introduced, what is the experimental phenomenon?

Ca2+2OH-+CO2=CaCO3(precipitation)+H2O
Precipitation dissolution!
CaCO3+H2O+CO2=Ca2+2HCO3-
