CAS:1343-98-2 | SILICIC ACID

Introduction of CAS:1343-98-2 | SILICIC ACID

Silicic acid was originally called metasilicic acid, chemical formula H2SiO3, formula 78.10. White amorphous powder, insoluble in water. It is a binary weak acid with an ionization equilibrium constant K1=2×1010(room temperature). Natural silicic acid exists in large quantities in the form of salt.

Single molecular silicic acid soluble in water, binary weak acid, in the solution gradually condensed to form insoluble polyacid, to obtain a colloidal solution, called "silicic acid sol", the latter with electrolyte, or in the appropriate concentration of silicate solution to add acid, then obtain silicic acid coagulation Chemicalbook glue, after dehydration porous solid, called "silica gel". It can be used as an absorber of gases and vapors, as a catalyst or as a carrier of other catalysts. Since silica does not combine with water, silicic acid is mainly prepared by reacting silicate solutions with strong acids.
