What is Downward Displacement of Water?
Answer Posted / devesh asrani
Downward displacement of water is a laboratory method of
preparation of hydrogen which is present dissolved in water.
Zinc granules are placed in a flask with two holes at the
top. Thistle funnel is passed through one hole and a
delivery tube through another. The delivery tube is attached
to a bee hive shelf in a shelf under water.Dilute
hydrochloric acid is added through the thistle funnel. small
bubbles are seen. This is how hydrogen gas is collected
Zn+HCl......ZnCl2+H2
