Question: Why should the total amount of liquids introduced into a test tube not exceed half the capacity of the test tube?
The total amount of liquids introduced into a test tube should not exceed half the capacity of the test tube to prevent the risk of overflowing or spilling. When liquids are added to a test tube, they occupy a certain volume, and as the volume of the liquid increases, the pressure on the tube walls also increases. If too much liquid is added, the pressure can exceed the capacity of the test tube, causing the liquid to overflow or spill. This can result in a waste of the reagents, affecting the accuracy of the experiment, and can also pose a safety hazard. Therefore, it is important to avoid overfilling test tubes and to use appropriate equipment to contain the liquids.
