Question

In the experimental set up to show that "CO2 is given out during respiration", name the substance taken in the small test tube kept in the conical flask. State its function and the consequence of its use.

Answer 1

Answer:

KOH is taken since it absorbs CO₂ from the surroundings

Explanation:

Germinating seeds are used because they use up the oxygen in the flask to respire and release carbon dioxide as a result, which is absorbed by KOH, causing the weight of KOH to increase. Potassium hydroxide is used in this experiment played the role of absorbtion of carbon-dioxide from the plant surrounding.

Answer 2

KOH is the substance taken in the small test tube kept in the conical flask.

FUNCTIONS- It absorbs CO2 produced by the germinating seed.

CONSEQUENCES- The water level rises in the test tube dipped in the beaker / partial vacuum is created.
