Question

When we blow carbon dioxide, lime water turns milky. List
the changes with the chemical reaction.​

Answer 1

Answer:The exhaled air containing carbon dioxide is the reason for the turning of lime water into milky colour.  The reaction is a combination reaction owing to the fact that calcium oxide and water react with each other to form only one single product i.e. calcium hydroxide.

Ca(OH)2(aq)+CO2(g)→CaCO3(s)+H2O(l)

is the formula

Explanation:

Answer 2

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.
