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 [H2xSiOx+2]n.

In chemistry, a silicic acid (/ s ɪ ˈ l ɪ s ɪ k /) is any chemical compound containing the element silicon attached to oxide (=O) and hydroxyl (−OH) groups, with the general formula [H 2x SiO x+2] n or, equivalently, [SiO x (OH) 4−2x] n.

Silicic acid is a silicon oxoacid. It is a conjugate acid of a trihydrogensilicate (1-). Orthosilicic acid has been reported in Rauvolfia serpentina, Rauvolfia verticillata, and other organisms with data available. A hydrated form of silicon dioxide. It is commonly used in the manufacture of TOOTHPASTES and as a stationary phase for CHROMATOGRAPHY.

Silicic acid, a compound of silicon, oxygen, and hydrogen, regarded as the parent substance from which is derived a large family—the silicates—of minerals, salts, and esters. The acid itself, having the formula Si(OH)4, can be prepared only as …

Dec 19, 2020 · Can someone please explain to me what is the differences between $\ce{Si(OH)4}$, $\ce{H4SiO4}$, and $\ce{SiO2.2H2O}$? I am currently studying sandstone acidizing geochemical models and this question came to me.

Jul 15, 2016 · Here, we report that Si (OH) 4, the simplest form of silicate, can stimulate human mesenchymal stem cells osteoblastic differentiation. We identified that miR-146a is the expression signature in bone cells treated with Si (OH) 4.

Jul 26, 2017 · Orthosilicic acid (Si (OH) 4) and its small condensation compounds are among the most important silicon compounds but have never been isolated, due to their instability. These compounds would...

Orthosilicic acid is an inorganic chemical that has the formula Si (OH)4. It is a chemical compound composed of silicon, oxygen, and hydrogen. Although it is infrequently seen, it is a crucial molecule in silica and silicates, as well as the precursor to other silicic acids [H2xSiOx+2]n.

We have identified silicic acid (Si (OH) (4)) as an important modifier of the absorbance signal of aluminium measured by graphite furnace atomic absorption spectrometry (GFAAS). The presence of Si (OH) (4) enhanced the signal by as much as 50%.
