Answer / rajkumar
It is the displacement of water in the downward direction.
Mostly it is used to collect the gas that is dissolved in
water. For the collection of water, the density of the gas
should be less than the density of water.

Answer / ruchira roy
In a chemical reaction when the water is displaced downward by the gas through the delivery tube, collecting in the jar (filled with water), this process is called downward displacement of water. This process is used for collecting gases which are less dense and insoluble in water.

Answer / al jaber
In any chemical reaction to collect gas using water in beakers and testtubes.The gas from the reaction travels along the delivery tube the gas bubbles through the water and will rise into the water the gas then pushes the water until the test tube is full of gas this pushing of water called downward displacement of water

Answer / manabendra
When water is displaced downward by the gas collecting in the jar, it is known as the downward displacement of water.

Answer / 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

Answer / nitin raj
The bubbles of hydrogen gas are transferred through the delivery tube and collected in the gas jar .This process is known as downward displacement of water

Answer / chris
What the Downward Displacement of water actually is is when
water is pushed downwards to allow an increase in gases
being able to move into a certain area. Therefore forcing
water out and creating room, the amount of water being
pushed away over a period of time is an indication of the
effect of substrate concentrate on the rate of enzyme
concentration because of the amount of gas released.

Answer / shirish sharma
The downward movement of water in a closed container or
test tube due to presence of another gas in the same
container which is lighter than water is called downward
displacement of water.

Answer / drama queen
its a method ov collecting a gas dats insoluble in water simply by allowing it 2 flow into a water fulled tub wid a collecting jar (gas jar) filled wd water over it....as da gas collects,water gets DISPLACED downwards.....
