Uses and Applications
Glass industry
> Serves as a flux for silica. It lowers the melting point of the mixture.
> Used to make bottle and window glass
water Softening
> Used to soften hard water by removing Magnesium and Calcium ions. These ions form insoluble precipitates with carbonate ions
Food industry
> It is a food additive (E500) used as acidity regulator, anti cracking agent and stabilizer
> Used in the production of sherbet powder
Others
> Used as wetting agent by brick industry to reduce the amount of water required to extrude the clay
> Act as foaming agent and abrasive in toothpastes
