Sodium Metasilicate

Sodium metasilicate is a member of the sodium compound family, according to the International Programme on Chemical Safety. A very basic compound, sodium metasilicate is used in a variety of industrial and household settings. While it is a cleaning and de-rusting solution, it is highly corrosive and should be handled with care. Sodium metasilicate is produced by fusing sand with sodium carbonate at very high temperatures, notes the International Programme on Chemical Safety. This produces a clear, white or grayish-white crystal solution. Sodium is a base, and therefore has a high pH level. When interacting with acid, sodium metasilicate will often neutralize that acid.

Description

Sodium metasilicate is a member of the sodium compound family, according to the International Programme on Chemical Safety. A very basic compound, sodium metasilicate is used in a variety of industrial and household settings. While it is a cleaning and de-rusting solution, it is highly corrosive and should be handled with care.

Sodium metasilicate is produced by fusing sand with sodium carbonate at very high temperatures, notes the International Programme on Chemical Safety. This produces a clear, white or grayish-white crystal solution. Sodium is a base, and therefore has a high pH level. When interacting with acid, sodium metasilicate will often neutralize that acid.

Sodium metasilicate is a highly corrosive substance, particularly when water is added. For this reason, it is used in a variety of settings. The compound is found as an ingredient in fireproofing mixtures, household cleaning, insecticides, fungicides and as a bleaching aid. The United States Food and Drug Administration has approved one form of sodium metasilicate, the pentahydrate form, for use in washing vegetables and fruits.
