Question

describe the experiment showing that carbon dioxide is liberated during respiration​

Answer 1

We can do a step of processes to show that CO2 is formed in respiration :-

Steps :-

1. Take some lime water(Ca(OH)2) in a test tube.

2. Take a pipe/ straw and blow some air from your mouth into the test tube.

Observation :-

You will observe that the lime water turns milky.

Results :-

The following reaction will take place -

Ca(OH)2 + CO2 ---------> CaCO3 + H2O

Hence proved
