Silicic acid (Cat No.: M049979) refers to a group of weakly acidic compounds containing silicon, oxygen, and hydrogen, generally represented as H₄SiO₄. It exists primarily in aqueous solution and is the fundamental building block of silicates and silica in nature. Silicic acid plays a key role in biomineralization, plant nutrition, and geochemical processes. Though unstable in isolated form, it polymerizes to form silica gels and glassy solids. It is also used in cosmetics, water treatment, and biomedical applications for controlled release and support materials.
