Question

what is the role of soda lime, KmNo4, carbolic acid and lime water in experiment for respiration
​

Answer 1

1.Soda lime- soda lime absorbs carbon dioxide and turns milky . ... hence we can conclude that carbon dioxide is released when plants respire . .
2.Carbonic acid- It plays an important role in the bicarbonate buffer system to maintain acid–base homeostasis
3. Lime water- Using lime water is a fun and easy way to test for the presence of carbon dioxide.

Answer 2

Carbon dioxide, also commonly known by its chemical formula CO2, is one of the major building blocks of life. It is usually found in its gaseous form, and is a major part of the plant and animal life cycle. CO2 is consumed by plants in photosynthesis and is produced by animals (like us!) during respiration. It is also expelled from the earth’s core during volcanic eruptions and exits a vehicle’s engine from its tailpipe when the motor is running. It’s considered a greenhouse gas, one of several compounds which contributes to global climate change. Carbon dioxide is all around us, and this simple experiment will help you see CO2 production by conducting a carbon dioxide test with two chemical reactions.
