Sodium bisulfite solution is a colorless to light yellow liquid. It has a certain acidity and is soluble in water and ethanol. The following is an introduction to the properties, uses, preparation methods, and safety information of sodium bisulfite solution:
Nature:
-Melting point: 58 ° C
-PH value: acidic
Usage:
-In the manufacturing of pulp and paper, sodium bisulfite solution can be used for bleaching and removing bleach residues from pulp.
-In the petroleum and chemical industries, sodium bisulfite solution is used to adsorb and remove harmful substances such as aldehydes, ketones, acids, and odors.
-In water treatment, sodium bisulfite solution can be used to remove ammonia, chlorine, and some heavy metal ions.
Method:
Sodium bisulfite solution can be prepared by dissolving sodium sulfite (Na2SO3) in water and then introducing sulfur dioxide (SO2). The reaction equation is: Na2SO3+SO2+H2O → 2NaHSO3.
Security information:
-Sodium bisulfite solution has certain irritancy and should be avoided from contact with skin and eyes. If accidentally touched, rinse immediately with plenty of water and seek medical attention.
-When storing, it should be sealed, kept away from ignition sources, and avoid contact with flammable substances.
-If a large amount of sodium bisulfite solution is accidentally splashed, please call emergency personnel immediately.
-When using and storing sodium bisulfite solution, please refer to the relevant safety technical manual.
