Description:
White crystalline powder, free from extraneous Matter with a faint odour of sulphur dioxide gas.
Application:
1.It is used as a preservative and antioxidant in food and is also known as E223
2.It is commonly used in homebrewing and winemaking to sanitize equipment. It is used as a cleaning agent for potable water reverse osmosis membranes in desalination systems. It is also used to remove chlormine from drinking water after treatment.
3.Concentrated sodium metabisulfite can be used to remove tree stumps. Some brands contain 98% sodium metabisulfite, and cause degradation of lignin in the stumps, facilitating removal.
