Question

how do silicic acid is prepared​

Answer 1

Silicic acids may be obtained by acidifying certain silicate salts like sodium silicate in aqueous solution. When heated they lose water to form silica gel. In the oceans, silicon exists primarily as orthosilicic acid (H4SiO4), and its biogeochemical cycle is regulated by the group of algae known as “diatoms”.
