SMBS/sodium pyrosulphite/sodium metabisulfite
English name: High Quality Sodium Metabisulfite Industrial Use
It is white or tiny yellow crystal powder. Its relative density is 1.4. The solubility is 54g/100mlwater at 20°C or 81.7g/100mlwater at 100°C,and the solution show acidity. It can solute in glycerine and little in alcohol. When exposed in air, it will oxidized into sodium sulfate, and can react with strong acid into sulfur dioxide gas and the salts. It is deliquescent, and will decompose when heated to 150°C.
|value of PH||4—4.6|
|heavy metal (Pb)%||≤0.002%|
|appearance||white or tiny yellow crystal powder|
Property: white or light yellow crystal powder, a strong smell of sulfur dioxide,relative density is 1.4, easy to dissolve in water and glycerin, water solution. It has acidity,and its solubility will become large while raising the temperature and is less to dissolve in ethanol.
