hii how can i prove that plants clean indoor air and how can i design an experiment to prove this?

Answer 1

You need to define what you mean by "clean air" if this is a scientific experiment.

Answer 2

Put a plant in a sealed container with a known air composition.

Expose the plant to normal conditions, it light, temperature etc

During this time use a probe to show the gas composition within the sealed container

Over time you will see the gas composition change.

This would be a costly experiment though.

If you were on a budget, you could use the following.

Put a plant into sealed container with a known amount of CO2
Put a sealed container with the same amount of CO2

Draw out 100CC of the gas composition from each and buuble each through Sodium Hydroxide. This will turn the CO2 in each sample into Sodium Carbonate. Now weigh the resulting solid, this gives the baseline.

Now expose the sealed containers to normal conditions

During the experiment, draw off 100CC of gas from each container, again bubble through Sodium Hydroxide and weigh the resulting solid.

In the plant container, as it uses up the CO2 the mass of the solid should decrease as less Sodium Carbonate is produced when the gas is bubbled through the Sodium Hydroxide.

Hope this helps

Answer 3

take a leafy plant and cover with a clear plastic bag to allow sunlight through put a piece of candle in the pot with the plant . Keep several strike anywhere matches inside the bag so you can light them from the outside. Light the candle and seal the bag quickly. As the candle burns it will run out of oxygen and produce a lot of carbon dioxide and monoxide. Wait several days and see if the candle will light. If it does then your plant has produced oxygen from the carbon dioxide and carbon monoxide.
There is your proof.

Answer 4

Put plants in an aquarium and close it up and use a CO2 extinguisher and feed some in to displace the air. The plants will absorber it and replace it with oxygen.

Answer 5

on the grounds that scientist (and absolutely everyone with any education or education in technological information) are the 1st to the two admit and teach the standard public that technological information does no longer coach something yet only promises help for or fails to grant help for a hypothesis i could question absolutely everyone claiming to be a scientist that could declare his/her test proved something. That mentioned if absolutely everyone ought to grant data for the non existence of something (the wonderful revolution in the historic past of technological information) alongside with ghost i could be very much inspired and carefully evaluate each and every of the climate of this international changing test.
