Question

What is the function of soda lime in the bottle'A' and why is limewater placed in bottle 'B'?​

Answer 1

Soda lime is kept in bottle 'A' so as to check the (presence of) passage of CO2 present in bottle 'B'. This is because soda lime has a tendency to absorb CO2 present in air. The limewater present in bottle 'B' shows that no CO2 is entering bottle C with the air passing through bottle c

Answer 2

Answer:

Soda lime is placed in bottle 'A' as it indicates the passage/presence of carbon dioxide in bottle A. Another property of soda lime is that is absorbs carbon dioxide that is present in the air. The clear limewater in bottle B indicates that the air that enters the flask C is free from carbon dioxide.
