Silicic acid can be made by reacting silicon dioxide with an alkaline solution, such as sodium hydroxide. This reaction forms sodium silicate, which can then be acidified to produce silicic acid.
Silicic acid
The reaction of H2SiO4, which is silicic acid, involves the dissociation of the molecule into its ions in water. The reaction can be represented as H2SiO4 -> 2H+ + SiO4^2-. Silicic acid is a weak acid and will partially dissociate in water.
Chlorine (Cl) is much more electronegative than silicon (Si). This means that chlorine exerts a much stronger "pull" on the electrons in a perchloric acid molecule than silicon does in a silicic acid molecule. The stronger pull makes it easier for a hydrogen ion (H+) to break away. The greater the degree of dissociation the stronger the acid. Perchloric acid dissociates completely in water, thus marking it as a strong acid. Silicic acid only dissociates partially, thus marking as a weak acid.
Silicic acid could occur as solution as well as solids. 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 an unstable solution in water; its molecules readily condense with one another to form water and polymeric chains, rings, sheets, or three-dimensional networks that constitute the structural units of silica gel and many minerals that have very low solubility in water.
Silicic acid is a weak acid, not a base. It can donate a proton in water to form silicate ions, making it slightly acidic in nature.
The chemical formula of silicon dioxide is SiO2.

No. Some igneous rocks were once referred to as "acidic" on the misconception that they contained elevated levels of silicic acid.
Silicic acid has shown some effectiveness in treating acne by reducing inflammation and promoting skin healing. However, more research is needed to fully understand its benefits and potential side effects.

HSiO3 is silicic acid, which is a weak acid formed by the combination of silicon, hydrogen, and oxygen atoms. It is commonly found in silicate minerals and can act as a precursor to various silicon compounds.
Igneous rocks are not an acid. Volcanic activity can release gases that can form acid on contact with water, including sulfur dioxide and carbon dioxide which form sulfuric and carbonic acid respectively. Igneous rocks were once divided into classifications of "acidic" and "basic" based on the idea that differing properties were a result of differing amounts of silicic acid. This idea has been abandoned as we now know it is silica rather than silicic acid that plays a large role in the properties of igneous rock.
