Fevicol is an adhesive marketed to carpenters that is designed to be used on woods, paper, cardboard, and fabrics. Fevicol is not water soluble. The glue has to be boiled in water before application.
gums are polymeric substances whereas fevicol is a polyvinyl alchol gum .It is not a polysaccharides.

Yes.
Fevicol is a PVA glue. PVA is relatively harmless, and the solvent is water. Some pva glues contain fungicides, so you don't want to drink it but the headline is "non-toxic".
The drying of Fevicol (a type of glue) is a physical change because it involves a change in the state of the substance from a liquid to a solid due to the evaporation of water or other solvents. Chemical changes involve the formation of new substances with different chemical properties.

No, it is not recommended to use a mixture of Fevicol and Fevibond to stick aquarium glasses. It is important to use a specialized aquarium silicone sealant that is safe for underwater use and able to withstand the pressure and moisture in an aquarium environment. Mixing different adhesives may compromise the structural integrity of the tank and harm the aquatic life inside.
Fevicol from the general appearance and smell looks like its is a compound of EVA Ethelene Vinyl Acetate along with some extenders, these offer excellent bonding properties and cure to a film which is peelable. The important property is that the adhesive has a porperty of whetting the substrate and hence it is excellent for porous sunstrates like wood.
If hydrochloric acid (HCl) reacts with Fevicol (polyvinyl acetate adhesive), the hydrochloric acid may break down the polyvinyl acetate polymer structure in the Fevicol, resulting in a release of acetic acid and some chlorine gas. This reaction may cause fumes and heat to be generated, leading to a potential safety hazard. It is not recommended to intentionally mix these substances.
