Answer:
When carbon dioxide is passed through lime water for a short time,it turns lime water milky due to formation of a white precipitate of calcium carbonate.
Step-by-step explanation:
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid. The cloudy white solution observed when CO2 is bubbled into limewater results from a reaction between Ca(OH)2 and either CO2 or H2CO3 to form an insoluble calcium carbonate precipitate.
