What is sodium hydrogen sulfite used for?

Sodium Bisulfite is a white, crystalline solid with a slight odor of rotten eggs. It is often in a liquid solution. It is used in making paper and leather, as a food preservative and in dye and chemical production.

Is sodium bisulfite hazardous?

Chemical Incompatibilities: Sodium Bisulfite Solutions may release toxic and hazardous fumes of sulfur oxides, including sulfur dioxide. Acute poisoning from sulfur dioxide is rare because the gas is easily detected. It is so irritating that contact cannot be tolerated.

Is sodium bisulfite harmful to aquatic life?

Toxicity tests showed that overfeed situations withsodium thiosulfate or sodium bisulfite can depress pH and dissolved oxygen, causing mortality of fish.

How do you neutralize sodium bisulfite?

Any spillages should be neutralized with soda ash, to prevent sulphur dioxide emission, and then be oxidized to neutral sulphate with sodium hypochlorite. Sodium metabisulphite should be used if dechlorinating chemical is required in powder form.

    Why are sulfites bad for you?

    Sulfites can trigger severe asthmatic symptoms in sufferers of sulfite-sensitive asthma. People deficient in sulfite oxidase, an enzyme needed to metabolize and detoxify sulfite, are also at risk. Without that enzyme, sulfites can be fatal.

    How do you make sodium sulfite solution?

    Preparation. Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. When conducted in warm water, Na2SO3 initially precipitates as a yellow solid. With more SO2, the solid dissolves to give the disulfite, which crystallizes upon cooling.
