A dehydrating agent is usually an acid which brings about loss of water molecule when used on an hydrated compound.
A chelating agent is usually an electron donour (ligand) which forms a complex by coordinating with a metal using two or more donor groups of a single ligand.
drying agent absorbs the water content while dehydrating agent lost the water content.

One natural chelating agent is tannic acid.
Not necessarily. Chelating agents can be neutral too. For example en (ethylenediamine), etc. The only condition for a ligand to be called a chelating agent is that it should coordinate with the metal in a manner so as to form a ring .

A ligand is an ion or molecule that binds to a central metal atom to form a coordination complex. The bonding usually involves the formal donation of one or more of the ligand's electron pairs. A chelating agent is a type of ligand.
yes it is a dehydrating agent but the problem is that phosphorous pentoxide not survives lastlong. Bcz it is very reative and unstable
Tertrasodium EDTA is a chelating and preservative agent.

You will have free metal ions.
Diphosphorus pentoxide (P2O5), otherwise known as phosphoric anhydride is most commonly used as a dehydrating agent for various organic syntheses.
