What will happen if bubbles of air are sent through lime water taken in a container?

Correct option is A

Correct Answer: A

Explanation:

• When bubbles of air are sent through lime water (which is a solution of calcium hydroxide), the carbon dioxide (CO₂) present in the air reacts with calcium hydroxide to form calcium carbonate (CaCO₃), which is an insoluble precipitate.
• This reaction causes the solution to turn milky, as calcium carbonate does not dissolve in water.
• The chemical reaction involved is: Ca(OH)₂+CO₂→CaCO₃ (s)+H₂O

Information Booster:

•  The presence of carbon dioxide is crucial for the formation of calcium carbonate.
  
•  Lime water is commonly used to test the presence of carbon dioxide, as the milkiness indicates CO₂.
  
•  Calcium carbonate is the compound responsible for the milky appearance.
  
• This test is widely used in laboratories to detect carbon dioxide gas.
