Sodium Chloride NaCI

Superiority:

Product Name: Sodium Chloride (NaCl)
Molecular weight：58.44
License Number：Y20190008765
Executive standard: "Chinese Pharmacopoeia" 2020 edition two
Properties: This product is colorless, transparent cubic crystal or white crystalline powder; odorless. This product is soluble in water and almost insoluble in ethanol.
Packing specification: 25kg/bag, 20kg/carton

 

Product Description: soluble in water and glycerin, slightly soluble in alcohol. At 25℃, 1g was dissolved in 2.8ml water, 2.6ml boiling water, 10ml glycerol, and very slightly dissolved in ethanol. Its solubility in water decreased due to the presence of hydrochloric acid and it was almost insoluble in concentrated hydrochloric acid. Aqueous solution is neutral, pHo6.7-7.3. Median lethal dose (rats, oral) was 3.75+/-0.43g/kg.

Purpose: Determination of silver nitrate reference. Microdetermination of fluorine and silicate. Used for high purity analysis. Routine blood tests. Liver function tests. Bacterial serological medium was prepared. Refrigerating mixture. Food preservation. A photograph. Analytical reagents, drop analysis of fluorine and silicate, chromatographic analysis reagents.

Matters needing attention

Overview of folding Hazards

This PRODUCT USUALLY DOES not BELONG to DANGEROUS goods, BUT in the case of especially low concentration, mixed with some gases, may appear explosion, combustion and other special and drastic chemical changes, thus causing danger. The ignition point of this product is not high, but the concentration of the explosion is more strict, usually, in the concentration of -0.00001% to -0.02458%, relatively easy to explode. Therefore, when conducting different dimensional chemical experiments, we should be extra careful and pay attention to safety.

 

Toxicity of folding

This product has no chemical toxicity, but excessive ingestion can cause cell dehydration and death in severe cases. LD50(rat oral) : 3.75±0.43g/kg.

 

Skin contact: Clean with water after skin contact.

 

Ingestion: In case of excessive consumption, drink more water (e.g., drink sugar water, drink salt boiled water) or use other measures (e.g., injection of normal saline [mass fraction of sodium chloride solution of 0.9%]) to maintain the body moisture, otherwise, the consequences are very serious (will show the symptoms of dehydration).

 

Folding fire protection measure

Danger characteristics: This product is a low toxic chemical products, not flammable, no special requirements for fire protection.

 

Harmful combustion products: no harmful combustion products.

 

Folding leakage emergency treatment

Emergency treatment: replace the bag in time.

 

Elimination method: clean, recycling can be.

 

Folding operation disposal and storage

Storage precautions: SHOULD be stored in cool, room temperature avoid light, ventilated dry place, can stack put, to prevent rain, not with acid and alkali mixed storage, stack bottom to lay wood, to moisture-proof, stack put height not more than two meters.

 

Folding contact control/personal protection

Respiratory protection: Wear a mask.

 

Eye protection: If sodium chloride crystals get into your eyes, flush them with plenty of water
