Vedclass · Answer

(B) $1$. In the experimental setup, a small test tube containing $KOH$ (potassium hydroxide) or lime water $(Ca(OH)_2)$ is placed inside the conical flask.$2$. The function of $KOH$ is to absorb the $CO_2$ produced by the germinating seeds, creating a partial vacuum that causes the water level in the delivery tube to rise.$3$. If lime water is used, its function is to detect the presence of $CO_2$. When $CO_2$ reacts with lime water, it turns milky due to the formation of insoluble calcium carbonate $(CaCO_3)$.

In the experimental setup to demonstrate that $CO_2$ is released during respiration, name the substance taken in the small test tube kept inside the conical flask. State its function and the consequence of its use.
