There are thousands of chemical reagents, which play an important role in medical, industrial, environmental governance and other fields. Many chemical reagents are dangerous. Generally, they are classified by the English letters on the label of the reagent bottle. Do you know what the letter “Xi” on the label means?[ Reagent Bottles 250ml,Laboratory Reagent Bottle,Chemistry Bottle Reagent,Reagent Bottle Lab,Screw Bottle Reagent Glass Bottle ]
Safety is relative. As experimenters, they often come into contact with chemical reagents and need to understand the characteristics of various reagents. The letter “Xi” on the label of the reagent bottle represents an irritating chemical reagent. This type of agent usually damages locally, and can cause systemic reactions when the stimulus is too strong.[ Reagent Bottles 250ml,Laboratory Reagent Bottle,Chemistry Bottle Reagent,Reagent Bottle Lab,Screw Bottle Reagent Glass Bottle ]
The solubility and concentration of chemical reagents determine the damage degree of the lesion. The solubility is related to the site of the poison, and the concentration is related to the degree of the lesion. Ammonia and hydrochloric acid with high solubility will immediately adhere to the local irritation when they come into contact with the moist eyeball conjunctiva and upper respiratory tract mucosa. Chlorine and sulfur dioxide with medium solubility will only infringe the eyes and upper respiratory tract at low concentrations, while high concentrations will infringe the whole body. Respiratory tract: Low concentrations of nitrogen dioxide and phosgene are less irritating to the upper respiratory tract, easily enter the deep part of the respiratory tract and gradually interact with water to cause irritation and corrosion to the lungs, often causing pulmonary edema. Direct contact with liquid irritating poisons can cause burns on the skin and mucous membranes.
Experimenters must observe the letters on the label of the reagent bottle before the experiment, understand the performance of the reagent, and take precautions when handling such chemical reagents to ensure their own safety.[ Reagent Bottles 250ml,Laboratory Reagent Bottle,Chemistry Bottle Reagent,Reagent Bottle Lab,Screw Bottle Reagent Glass Bottle ]
