On the reagent rack in the laboratory, there is a type of white crystal that is often overlooked - it does not have dazzling labels, nor does it involve complex synthesis processes, but it is like a silent "polymath", quietly supporting the normal operation of dozens of industries such as food preservation, pharmaceutical synthesis, and water purification. It isSodium bisulfiteThere is a smell of sulfur dioxide. It has an unpleasant odor. Exposure to air results in the loss of some sulfur dioxide and oxidation to sulfate. Dissolve in 3.5 parts of cold water, 2 parts of boiling water, and approximately 70 parts of ethanol. The aqueous solution is acidic with a relative density of 1.48 and a CAS number of 7631-90-5. Store in a sealed, dry, and cool place.

Sodium bisulfiteNot only as a reagent, but also as a lubricant for the industry, the "guardian of freshness" in the food industry: as a legal food additive, it can inhibit microbial growth and delay food oxidation and deterioration - from the preservation of fresh fruits and vegetables to the bleaching and brightening of dried fruits and preserves, it has its presence; The 'key assistant' in pharmaceutical synthesis: it is an efficient reducing agent in the intermediate synthesis of drugs such as aspirin and vitamin C, helping to construct the core molecular structure; A "purification expert" in water treatment: capable of quickly removing residual chlorine from water, protecting equipment such as reverse osmosis membranes, and degrading some organic pollutants; The "basic partner" of the laboratory: In quantitative analysis, it is a commonly used reducing agent in titration experiments, which helps with accurate chemical detection. It is also used as a reducing agent, preservative, disinfectant, and bleach. Used for organic bleaching and food preservation, as a reducing agent in industries such as dyeing, papermaking, leather making, and chemical synthesis, and as a fungicide in the brewing and beverage industries. Used for the production of saccharin, spices, and hydroxylamine hydrochloride. Behind these scenarios, there is a need for a sodium bisulfite with stable purity and controllable impurities - a slight deviation may cause food spoilage, experimental data deviation, and even affect production safety.

Sodium bisulfiteCorrosive and irritating, can lead to blindness, can cause asthma, and is harmful to the environment. During operation, it is necessary to operate in a sealed environment with local ventilation. Prevent dust from being released into the workshop air. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Avoid generating dust. Avoid contact with oxidants, acids, and bases. Equip with emergency response equipment for leaks. Empty containers may contain residual harmful substances. Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. Protect from direct sunlight. Sealed packaging. It should be stored separately from oxidants, acids, and bases, and avoid mixing storage. Not suitable for long-term storage to avoid spoilage. The storage area should be equipped with suitable materials to contain leaked materials.
