Silica gel is a translucent or chalky grain of white or yellowish color (due to impurities), is fragile when dried, slightly soluble and does not swell in water and organic solvents. This is a dried gel formed from supersaturated solutions of silicic acids. Solid hydrophilic sorbent. By its struc..
Silicic acid is theoretically a compound of silicon oxide and water. Moreover, the ratio of these components can be very diverse. Therefore, in general, their composition can be represented by the formula. In this case, silicic acids with the presence of different amounts of silicon oxide and water..
