Character:
White to light yellow granular, stick or powder.Has the water absorbability.Heated to 320 ℃ above decomposition.Slowly in the air oxidation of sodium nitrate.In weak acid decomposition released three brown nitrous oxide gas.In 1.5, 0.6, cold water boiling water, slightly soluble in alcohol.Aqueous alkaline pH around 9.Relative density 2.17.Melting point is 271 ℃.With oxidation, contact with the organic matter can combustion and explosion, and emit toxic and irritant peroxide nitrogen and nitrogen oxide gases.Medium poison, median lethal dose (rats, through the mouth) 180 mg/kg.
Usage:
Chromatographic analysis.Drop analysis to mercury, and potassium chlorate.The purpose of the sodium nitrite and harmDiazotization reagents.The nitrosation of reagent.Soil analysis.Liver function test in the determination of serum bilirubin.Silk, linen bleaching agent, metal heat treatment agent;Steel corrosion inhibitor;Cyanide poisoning antidote, and laboratoryAnalysis reagent, used as a hair in the meat products processing agent, anti microbial agent, preservatives.In such aspects as bleaching, electroplating and metal processing application, known as industrial salt.
