Silicic acid(CAS: 14807-96-6)

Silicic acid, with the CAS number 14807-96-6, is a weak acid composed of silicon, oxygen, and hydrogen. Its chemical formula is typically represented as H4SiO4. It is a colorless, odorless solid that is soluble in water and commonly found in nature as a component of silicates. Silicic acid exhibits amphoteric properties, meaning it can act as both an acid and a base under different conditions.

Silicic acid is widely used in various industries. In pharmaceuticals, it serves as an antacid and is used in some topical treatments. It is also employed in the food industry as a stabilizer and acidulant. In research, it is used for pH adjustment and in the synthesis of silicon-based compounds. Additionally, it finds applications in the production of ceramics, glass, and as a component in some cleaning products.

Silicic acid is generally considered safe when used in appropriate concentrations and under proper handling conditions. It has low toxicity and is not classified as a hazardous substance. However, prolonged exposure to high concentrations may cause skin or eye irritation. Safety data sheets recommend using protective gloves and goggles when working with it, and ensuring good ventilation in enclosed spaces.

Silicic acid should be stored in a cool, dry place away from direct sunlight. It is stable under normal storage conditions but should be kept in a sealed container to prevent moisture absorption. Maintaining a temperature range of 15-25°C and a humidity level below 60% is recommended. Avoid exposure to incompatible materials and ensure proper labeling for safe handling.
