Question

23. Study the given figure and answer the following questions.
(a) Which gas is collected in the gas jar?
(b) Why is it collected by downward displacement of water?
(c) Write any two uses of it.​

Answer 1

Answer:

Hydrogen is collected by downward displacement of water as it is less denser than water. Hence it comes out at the surface of water . It is insoluble in water so it does not dissolve in water. In case of displacement with air, it is not possible even if hydrogen is lighter than air (14.5 times lighter than air).
