What is Silicic acid?
Silicic acid, a compound of silicon, oxygen, and hydrogen, thought to be the mother or father substance from which is derived a big household of silicates of minerals, salts, and esters. The acid itself, having the formulation Si(OH)4, might be ready solely as an unstable answer in water; its molecules readily condense with each other to kind water and polymeric chains, rings, sheets, or three-dimensional networks that constitute the structural models of silica gel (q.v.) and lots of minerals which have very low solubility in water.
A number of esters of silicic acid, made out of alcohols and silicon tetrachloride, are thermally steady liquids employed as lubricants and hydraulic fluids.
