Hydrogen Peroxide Bleach Experiment
Peroxide and Bleach Experiment
Experimental Preparation
To experiment with peroxide and bleach, hydrogen peroxide and bleach are necessary. In addition, several clean test tubes, several droppers, and protective equipment such as goggles, gloves, etc. need to be prepared for safety.
Experimental Steps
1. Take three test tubes and label them A, B, and C.
2. Drop an appropriate amount of hydrogen peroxide into the test tube A with a dropper, and observe its shape. It is also a colorless and transparent liquid, and there is no special odor.
3. Inject an appropriate amount of bleach into the test tube B, it can be seen that it is also a colorless liquid, but there is a pungent smell, which is the smell of the chemical components contained in the bleach.
4. Slowly add the bleach in the test tube B to the hydrogen peroxide in the test tube A dropper dropwise, and observe the phenomenon closely. At this time, it can be seen that there are bubbles emerging rapidly in the mixed liquid, which seems to be gas formation.
Experimental Principle Exploration
The chemical formula of hydrogen peroxide is $H_ {2} O_ {2} $, and its molecular structure contains peroxide bonds (-O-O-), which are more active. The bleach contains sodium hypochlorite ($NaClO $) and other components. When hydrogen peroxide is mixed with bleach, sodium hypochlorite reacts chemically with hydrogen peroxide. Sodium hypochlorite is oxidizing, and hydrogen peroxide is both oxidizing and reducing. In this reaction, hydrogen peroxide is oxidized and sodium hypochlorite is reduced to produce oxygen and other substances, which is the reason for the formation of bubbles. The possible chemical reaction equation is: $NaClO + H_ {2} O_ {2} = O_ {2} ↑ + NaCl + H_ {2} O $.
Experimental precautions
1. During the experiment, be sure to wear goggles and gloves. Because both hydrogen peroxide and bleach are corrosive, if accidentally splashed on the skin or eyes, it will cause harm to the human body.
2. The operation needs to be cautious. When adding liquid dropwise, it should be slow to avoid the reaction being too violent and causing the liquid to splash out.
3. After the experiment is completed, the remaining liquid should not be dumped at will. It should be properly handled in accordance with the regulations of the laboratory to prevent pollution to the environment.
