Sodium silicate is a white solid that is soluble in water, producing an alkaline solution. There are many kinds of this compound, including sodium orthosilicate, Na 4 SiO 4; sodium metasilicate, Na 2 SiO 3; sodium polysilicate, (Na 2 SiO 3) n; sodium pyrosilicate, Na 6 Si 2 O 7, and others. All are glassy, colourless and dissolve in water. Sodium silicate is stable in neutral and alkaline solutions.
