Storage Conditions
Seal and store in a cool, dry and well-ventilated warehouse, far away from ignition sources and heat. Avoid mixed storage and transportation with alkalis, oxidants and other chemicals to prevent moisture absorption which may affect product performance.
2. Physical Properties
The melting point of sodium bisulfate is about 58.5℃. When heated to 315℃, it decomposes to produce sodium sulfate, sulfur trioxide and water. It has strong hygroscopicity and good water solubility, with obvious exothermic phenomenon during dissolution in water. Its solid form has good stability and is not easy to deteriorate under normal temperature and pressure.
3. Main Uses
● Industrial Field
It can be used as an acidic cleaning agent for descaling and derusting of metal surfaces; as an electroplating auxiliary to adjust the pH value of electroplating solution and improve the quality of electroplating coating; as a pH regulator for water treatment, applied to the pH adjustment of industrial circulating water and wastewater; it can also be used in chemical production processes such as sulfate manufacturing and dye intermediate synthesis.
