It is a porous material. Silica gel is a suitable adsorbent for water, alcohol, phenols, amines, and so on. That does this through hydrogen bonds.
WebThe process involves conversion of monomers into a colloidal solution ( sol) that acts as the precursor for an integrated network (or gel) of either discrete particles or network … WebGelatin is produced from the partial hydrolysis of collagen. Collagen is the most abundant protein in the body. It is a key structural component in many of our tissues, including our tendons and our bones. This may, at first, sound contradictory – how can collagen provide structure to hard tissues like bone, when gelatin is, by definition, a gel?
