CO2 + Ca(OH)2 → CaCO3 + H2O + heat (in the presence of water)
Each mole of CO2 (44 g) reacting with calcium hydroxide produces one mole of water (18 g).
The reaction can be considered as a strong-base-catalysed, water-facilitated reaction.
The reaction mechanism of carbon dioxide with soda lime can be decomposed in three elementary steps:
1) CO2 (g) → CO2 (aq) (CO2 dissolves in water - slow and rate-determining)
2) CO2 (aq) + NaOH → NaHCO3 (bicarbonate formation at high pH)
3) NaHCO3 + Ca(OH)2 → CaCO3 + H2O + NaOH ((NaOH recycled to step 2)
This is for LIME SODA
