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".
Methyl mercury is more toxic to humans than inorganic mercury. Methyl mercury is a highly toxic organic form that can accumulate in living organisms and bioaccumulate in the food chain, leading to potential health risks when consumed by humans. Inorganic mercury compounds are generally less toxic and less likely to bioaccumulate.
NO. Hydrogen gas is non-toxic. However, it can displace oxygen (and if hot enough burn in it) and thus can be an asphynxant in large quantities. But hydrogen by it self is not toxic at all.
Silver is not considered toxic, and it is not explosive under normal conditions. However, silver compounds can be toxic if ingested in large quantities. Silver nitrate, a common silver compound, can be explosive when exposed to heat or in certain conditions.
once again...this question CANNOT be answered as is, it needs to be more specific. -are you asking about oral, demal or inhalation toxicity? -are you asking about acute toxicity, chronic toxicity, or carcinogenic toxicity? -if asking about acute toxicity, are you asking about slightly toxic, moderately toxic, or highly toxic? -what is the context: mineral collection, stone carving, or mining?
A larger LD indicates a less toxic substance, because it takes more of the substance to kill.
Yes.
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.

When hydrochloric acid (HCl) reacts with Fevicol (polyvinyl acetate), a chemical reaction does not occur because Fevicol is a polymer made of repeating vinyl acetate units and does not contain any functional groups that can react with HCl. The HCl may not be able to break down the polymer structure of Fevicol due to the lack of reactive sites on the polymer chain. Therefore, no significant chemical reaction would take place between HCl and Fevicol.
Drying of fevicol is a chemical change obviously !! Its because we cannot bring back the original properties of fevicol whatsoever we do to it !!! ---------------------------------------------------- But evaporation of solvents is a physical process.

No, You cannot mix fevicol and fevibond because both of them have different media. i.e. fevicol is water-based while fevibond is rubber-based adhesive. Aquarium has to be filled with water and so, you cannot use fevicol as fevicol is likely to melt again within few hours. Its better if you go for feviquik first and stick the glasses and then make a lining of fevibond to ensure no water-leakage.
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.
