What is Si(OH)4? Important knowledge about Si(OH)4

  1. Definition of Si(OH)4
    Si(OH)4, also known as silicic acid, is a chemical compound containing silicon and hydroxyl. Its name in English is Silicic acid. The atomic mass of silicon is 28.0855 and the atomic mass of hydroxyl is 17.00734, therefore the molecular mass of Si(OH)4 is about 96.11 g/mol. The molecular structure of this compound includes one silicon atom linked to four hydroxyl atoms, creating a tetravalent structure. There are no ions in the structure of Si(OH)4 because it’s a non-ionizing compound.

  2. Properties of Si(OH)4
    Si(OH)4 is a colorless, odorless liquid. Its pH level is very high, indicating strong acidity. This compound is stable under standard conditions, but it can decompose when heated. The chemical properties of Si(OH)4 include its ability to react with bases to form silicates and water, and to react with esters to form silicates.

  3. Common chemical equations involving Si(OH)4
    Since Si(OH)4 is not a metal, it cannot participate in metal reactions. There are also no examples of reactions with acids, non-metals or salts because Si(OH)4 does not react with these substances.

  4. Synthesis of Si(OH)4
    Si(OH)4 is not commonly produced in traditional chemical laboratories because this process requires complicated and specialized methods. The primary industrial synthesis of Si(OH)4 involves the hydrolysis of tetrachlorosilane (SiCl4) in a water environment.
