Question

Is Fe(NO3)3 ionic Or covalent

Answer 1

Fe(NO3)3 is an ionic compound with Fe3+ cations and NO3- anions, though the NO3- itself has covalent bonds.

Step-by-step explanation:

The compound Fe(NO3)3 is considered ionic because it consists of a metal cation Fe3+ and the polyatomic anion NO3−. However, it is important to note that within the nitrate anion (NO3−), there are covalent bonds between the nitrogen and oxygen atoms. This is due to compounds like Fe(NO3)3 having ions that are composed of atoms held together by polar covalent bonds, which then form ionic compounds with other ions of opposite charge.

When Fe(NO3)3 dissolves in water, it dissociates into Fe3+ cations and NO3− anions. This behavior is typical for ionic compounds and is well illustrated by the soluble nature of all nitrates, as per solubility rules. The formation of compounds like Fe(OH)3 and NaNO3 in reactions also demonstrate the ionic character of these materials, since they involve the exchange and separation of ions in solution.

Answer 2

Fe(NO3)3 is ionic.

Step-by-step explanation:

Ionic bond:

Ionic bond is formed when oppositely charged ions attract each others i.e negative and positive ions.

We know that a neutral atom consist of equal number of proton and electron, cancel the charge of each other that is equal in magnitude and make the atom neutral or we can say that net charge is zero.

But when the atom lose or gain the electron, imbalance of neutron electron occur so charge will not remain zero and atom is no more to be said neutral.

In given compound Fe(NO3)3 the Fe is act as cation while nitrate is act as anion.

3Fe+ (Cation)

3NO3 ∧ -1 (anion)

3Fe∧+1 + 3NO3 ∧ -1 → Fe(NO3)3

Another example of ionic compound:

Now consider the sodium chloride which is an ionic compound. It is formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.

Na+ (cation)

Cl- (anion)

NaCl

Covalent bond:

Covalent bond involve the sharing of electrons between the atoms. It is also called molecular bond. These electron pairs are called bonding electrons are shared pair of electrons.
