Question

What is observed when carbon dioxide is passed through (i) water (ii) lime water. Also write the chemical

equations for the reactions that take place.​

Answer 1

Answer:

when co2 is passed through water then carbonic acid is formed.

H2o + co2 = H2CO3. combination reaction.

when co2 passed through lime water, it turns milky due to formation of calcium carbonate.

Ca(OH)2 + CO2 = CaCO3 + H2O

Answer 2

Answer:

when carbon dioxide is passed through lime water , it forms white precipitate of calcium carbonate Ca(OH).
