Q: What is Sodium Hydrosulfite?

A: Sodium dithionite (also known as sodium hydrosulfite) is a white crystalline powder with a weak sulfurous odor. Although it is stable under most conditions, it will decompose in hot water and in acid solutions. It can be obtained from sodium bisulfite by the following reaction:

2 NaHSO₃ + Zn → Na₂S₂O₄ + Zn(OH)₂

Q:What is other names for Sodium Hydrosulfite?

A: Sodium Dithionite

Q: What is Structure Sodium Hydrosulfite?

A: Raman spectroscopy and single-crystal X-ray diffraction studies of sodium dithionite in the solid state reveals that it exists in different forms. In oneanhydrous form, the dithionite ion has C 2 geometry, almost eclipsed with a 16º O-S-S-O torsional angle. In the dihydrated form (Na₂S₂O₄.2H₂O), the dithionite anion has a shorter S-S bond length and a gauche 56º O-S-S-O torsional angle.

Q: What is Sodium Hydrosulfite reactions?

A: This compound is a water-soluble salt, and can be used as a reducing agent in aqueous solutions. It is used as such in some industrial dying processes, where an otherwise water-insoluble dye can be reduced into a water-soluble alkali metal salt. The reduction properties of sodium dithionite also eliminate excess dye, residual oxide, and unintended pigments, thereby improving overall colour quality. Reaction with formaldehyde produces Rongalite, which is used as a bleach, in, for instance, paper pulp, cotton, wool, Leather, Chrome Tanning agent and kaolin clay.

Na₂S₂O₄ + 2 CH₂O → 2 HOCH₂SO– 2 + 2 Na+

Sodium dithionite can also be used for water treatment, gas purification, cleaning, and stripping. It can also be used in industrial processes as a sulfonating agent or a sodium ion source. In addition to the textile industry, this compound is used in industries concerned with leather, foods, polymers, photography, and many others. Its wide use is attributable to its low toxicity LD50 at 5 g/kg, and hence its wide range of applications.

Q: How to make Sodium Hydrosulfite?

A: Sodium dithionite is often used in physiology experiments as a means of lowering solutions' redox potential (Eo' -0.66 V vs NHE at pH 7). Potassium ferricyanide is usually used as an oxidizing chemical in such experiments (Eo' ~ 436 mV at pH 7). In addition, sodium dithionite is often used in soil chemistry experiments to determine the amount of iron that is not incorporated in primary silicate minerals. Hence, iron extracted by sodium dithionite is also referred to as "free iron." The strong affinity of the dithionite ion for bi- and trivalent metal cations (M2+, M3+) allows it to enhance the solubility of iron, and therefore dithionite is a useful chelating agent. When you heat the reaction, rainbow colors emerge due to the high transition states of energy.

Q: What is Sodium Hydrosulfite Precautions?

A: Keep away from heat and ignition sources. Harmful if swallowed. Avoid breathing vapors. Use with adequate ventilation. Avoid contact with eyes, skin, and clothes. Wash thoroughly after handling. Keep container closed.

FIRST AID After breathing: breathe fresh air. consult with your doctor if you do not feel well. after contact with skin: wash with plenty of water. Remove clothing terkompaminasi. After contact with eyes: rinse with water that is more banayak with the eyelid wide open. Contact your eye doctor. After the swallowing: immediately give the victim banayak drinking water. Call your doctor. Laxative: Sodium sulfate (1 tablespoon 1 / 4 1 water) Action Against spills and leaks Precautions related to personnel: Avoid contact with material. Avoid formation of dust, do not inhale dust, ensure supply of fresh air in a closed room. Environmental protection measures: Do not allow to enter sewerage system. procedures for cleaning / absorption: Take in the dry state, forward it to a disposal, clean the affected area.
