Observe the experimental setup shown below. Name the chemical indicated as ‘X’ that can absorb the gas which is evolved as a byproduct of respiration
- Ca (OH) 2
- K 2 CO 3
- This is an activity to show that Carbon Dioxide is necessary for photosynthesis .
- Carbon dioxide is a gas that is released as a byproduct of respiration in both humans and plants.
- KOH is kept in a watch glass under a bell jar to absorb all CO2 present in the bell jar.
