Most chemical reagents are flammable, explosive, volatile, or toxic. Therefore, it is necessary to standardize the reagents. In order to achieve accurate experimental results, the following rules should be observed when taking reagents to ensure that the reagents are not contaminated. And not degenerate:
(1) The reagent cannot be in contact with the hand.
(2) To use a clean medicine spoon, a measuring cylinder or a dropper to take reagents, it is absolutely not allowed to use the same tool at the same time and continuously use a variety of reagents. After taking one reagent, the tool should be washed (the spoon should be dried) before another reagent can be used.
(3) After the reagent is taken, be sure to close the stopper. Do not put the wrong bottle cap and the dropper. Do not allow the crown to be worn. After use, put the bottle back to the original position.
(4) The removed reagent can no longer be returned to the original reagent bottle.
In addition, the use of reagents should be based on the spirit of saving, as little as possible, so that it is easy to operate and carefully observe the phenomenon, but also get better experimental results.
