Final answer:
Sodium bicarbonate can be used to increase the concentration of carbon dioxide for experiments related to photosynthesis rate in plants.
Step-by-step explanation:
Sodium bicarbonate, also known as baking soda, can be used to increase the concentration of carbon dioxide (CO2) in water for experiments related to photosynthesis rate.
During photosynthesis, plants use CO2 from the surrounding environment, along with sunlight and water, to produce glucose and oxygen. By adding sodium bicarbonate to the water, it releases CO2 gas, providing higher levels of CO2 for the plants to utilize during photosynthesis. This can be particularly useful in experiments investigating the effect of varying CO2 concentrations on photosynthesis rate.
However, it's important to note that high concentrations of sodium bicarbonate can be harmful to plant cells, so it should be used in controlled amounts and not in natural settings.
