In chemistry, a silicic acid is any chemical compound containing the element silicon attached to oxide (=O) and hydroxyl (−OH) groups, with the general formula [H2xSiOx+2]n or, equivalently, [SiOx(OH)4−2x]n. Orthosilicic acid is a representative example. Silicic acids are rarely observed in isolation, but are … See more Silicic acids can be seen as hydrated forms of silica, namely 2 H2xSiOx+2 = SiO2·(H2O)x. Indeed, in concentrated solutions, silicic acids generally polymerize and condense, and ultimately degrade to silicon dioxide and See more • Boric acid See more Silicic acid was invoked by Jöns Jacob Berzelius in the early 19th century to explain the dissolution of silicon dioxide (silica, quartz) in water, namely through the See more Crystalline silicic acids can be prepared by removing the sodium cations from solutions of sodium silicates with an ion-exchange resin, or by treating sodium silicates with … See more WebTo balance NaOH + H2SO4 = Na2SO4 + H2O you'll need to watch out for two things.
