Question

In the experiment to show that carbon dioxide is produced during respiration by germinating seeds, the alkali solution kept in a small test-tube absorbs
(1) only O2 gas
(2) only CO2 gas
(3) both O2 and CO2 gases
(4) neither O2 nor CO2 gases

Answer 1

Answer:

option (b) is correct...

Explanation:

The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually, the germinating seeds respire and produce CO2, which is absorbed by KOH solution. This creates a vacuum in the conical flask. The air present in the bent glass tube moves into the conical flask. This pulls the water in the bent tube further up.....
