In an experiment demonstrating the evolution of oxygen in Hydrilla, sodium bicarbonate is added to water in the experimental set-up. What would happen if all other conditions are favourable.

A

Amount of oxygen evolved decreases as carbon dioxidein water is absorbed by sodium bicarbonate

B

Amount of oxygen evolved increases as the availability of carbon dioxide increases

C

Amount of oxygen evolved decreases as the availability of carbon dioxide increases

D

Amount of oxygen evolved increases as carbon dioxide in water is absorbed by sodium bicarbonate

Text Solution

Verified by Experts

The correct Answer is:
B
The addition of `NaHCO_3` to water in the given experimental set-up causes the availability of more `CO_2` for photosynthesis. Thus, amount of oxygen evolved increases.
