Orthosilicic acid (/ˌɔːrθəsɪˈlɪsɪk/) is an inorganic compound with the formula Si(O H)₄. Although rarely observed, it is the key compound of silica and silicates and the precursor to other silicic acids [H_2xSiO_x+2]_n. Silicic acids play important roles in biomineralization and technology.^[2]^[3]^[4] It is the parent acid of the orthosilicate anion SiO⁴⁻
₄.
