Explore: Silicic Acid

In chemistry, a silicic acid (/sɪˈlɪsɪk/) is any chemical compound containing the element silicon attached to oxide (=O) and hydroxyl (−OH) groups, with

precursor to other silicic acids [H2xSiOx+2]n. Silicic acids play important roles in biomineralization and technology. It is the parent acid of the orthosilicate

to carbonates by weathering and sedimentation. The production of sulfuric acid from anhydrous calcium sulfate produces calcium silicates. Upon being mixed
