Silicic acid is a chemical compound. Silicic acid is the general name for a family of chemical compounds containing the element silicon attached to oxide and hydroxyl groups. This family of compounds have the general formula [SiO(OH)]. Some simple silicic acids have been identified, but only in very dilute aqueous solution, such as metasilicic acid (HSiO), orthosilicic acid (HSiO, pK=9.84, pK=13.2 at 25 °C), disilicic acid (HSiO), and pyrosilicic acid (HSiO); however in the solid state these probably condense to form polymeric silicic acids of complex structure.
