ORTHOSILICIC ACID Meaning and
Definition
-
Orthosilicic acid is the chemical compound with the formula Si(OH)4. It is a hydrate of silica, where the central silicon atom is bonded to four hydroxyl groups (OH). Also commonly known as soluble silica or silicic acid, orthosilicic acid is a weak acid that exists in aqueous solution.
Orthosilicic acid is typically formed by the hydrolysis of silicon compounds, such as silicates or silica, in the presence of water. It can be found naturally in various sources, including mineral waters, plants, and certain types of rocks.
In terms of its chemical properties, orthosilicic acid is amphoteric, meaning it can act as both an acid and a base. It readily donates one or more hydroxyl groups to function as a weak acid, while it can also accept protons to act as a base and form silicate anions.
Orthosilicic acid is of interest due to its potential health benefits. It is believed to have a role in the formation, maintenance, and integrity of connective tissues, such as skin, hair, and nails. As a result, it is often used as an ingredient in various cosmetic and dietary supplements claiming to promote healthier skin, hair growth, and stronger nails. However, more research is needed to fully understand its exact mechanisms and benefits.
Etymology of ORTHOSILICIC ACID
The word "orthosilicic" comes from the combination of two Latin and Greek roots: "ortho-" and "silicic".
- "Ortho-" derives from the Greek word "orthos", meaning "correct" or "straight".
- "Silicic" comes from the Latin word "silici-" which is connected to "silex", meaning "flint" or "hard stone".
"Silicic" refers to compounds containing silicon, an element known for its presence in rocks and minerals. By combining "ortho-" with "silicic", the term "orthosilicic" suggests correct or straight formation of silicic, indicating the precise structure or arrangement of silicon atoms.
"Orthosilicic acid" specifically refers to a type of silicic acid, which is a compound formed when silica (SiO2) dissolves in water.
