  • B During respiration carbon dioxide entered C
  • C Oxygen reacts with lime water to produce milkiness
  • D Soda lime did not remove carbon dioxide from air
  • E The delivery tubes were not well connected
Correct Answer: Option A

Lime water turns milky when carbon dioxide reacts with calcium hydroxide (present in lime water) to form calcium carbonate, which is insoluble and appears as a milky precipitate. Plants produce carbon dioxide during respiration, which could cause this reaction if the container was exposed to the plant.
