NaNO2 Sodium Nitrite 27 MT / 20 GP 25 KG/ BAG Used for Dyeing Assistant
Sodium nitrite (NaNO2) is often used for dyeing and preserving foods such as fish and meat. Pure sodium nitrite is a white to light yellow crystal. It has very good water solubility and hygroscopicity. The aqueous solution is weakly alkaline, with a pH of about 9, easily soluble in liquid ammonia, and slightly soluble in organic solvents such as ethanol, and methanol. Sodium nitrite has a salty taste and is used to make fake table salt. In the air, sodium nitrite is slowly oxidized to sodium nitrate (NaNO3), which is a strong oxidant. Sodium nitrite is easy to explode in contact with organic matter.
