No simple silicic acid has ever been identified, since these species are primarily of theoretical interest. Depending on the number of silicon atoms present, there are mono- and polysilicic (di-, tri-, tetrasilicic, etc.) acids. Well defined silicic acids have not been obtained in a form that has been characterized by X-ray crystallography.

Orthosilicic acid (/ ˌ ɔːr θ ə s ɪ ˈ l ɪ s ɪ k /) 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 2x SiO x+2] n. Silicic acids play important roles in biomineralization and technology.
Screenshot of the CAS Common Chemistry database with information about caffeine ().. A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.

Values in the infobox are compared with values reported in literature, and when the values match, the revision is stored in the index for chembox and the index for drugbox, respectively. This is typically done for values that are 'immutable' (e.g., the boiling point of a chemical compound: the boiling point of water under standard conditions is ...
The possible products include SiH 4 and/or higher molecules in the homologous series Si n H 2n+2, a polymeric silicon hydride, or a silicic acid. Hence, M II Si with their zigzag chains of Si 2− anions (containing two lone pairs of electrons on each Si anion that can accept protons) yield the polymeric hydride (SiH 2 ) x .
