Orthosilicic

Part of speech: adjective

Definitions

1. Relating to or containing orthosilicic acid, the simplest silicon acid, with the formula H4SiO4 and a single silicon atom at its centre
2. Describing the chemical form of silicic acid in which one silicon atom is bonded to four hydroxyl groups, as in H4SiO4
3. Of or pertaining to orthosilicic acid, a monomeric silicon-based acid whose molecules carry four hydroxyl groups around one silicon atom

Etymology: "Orthosilicic" is a chemistry term built from two parts. The first, "ortho-", comes from ancient Greek "orthos", meaning straight or upright, and in chemistry it marks the most fully hydrated or simplest form of an acid. The second part, "silicic", refers to silicon, the element, with the "-ic" ending used for acids containing that element. Put together, "orthosilicic" names the simplest silicon acid, the one with the highest proportion of water in its structure. Chemists use the prefix in the same way for related acids such as "orthophosphoric" acid, so the word follows a standard naming pattern rather than arising from a single event or person.
