In chemistry, an amphoteric species is a molecule or ion which can react as an acid as well as a base. This word is derived from the Greek word amphotericin which is meant for both: Many metals like zinc, tin, lead, aluminium, beryllium, etc formamphoteric oxides or hydroxides. Here both V 2 O 5 and C r 2 O 3 can show the property of acidic. Further, we know that higher the polarizing power of the cation (higher for higher oxidation state of the similar of size cations) more will be the covalent character. so MnO is the most ionic and Mn2O7 is the most covalent.

(iv) in covalent compounds, fluorine can form a single bond only while oxygen. forms double bond. Solution: Option (iv) is the answer. 20 Answer. M n has +7 oxidation state in M n2. . O7. . and +2 in M nO. In low oxidation state of the metal, some of the valence electrons of the metal atom are not involved in bonding. Hence, it can donate electrons and behave as a base. On the other hand, in higher oxidation state of the metal, valence electrons are involved in bonding and are.

Why Mn2O3 is basic whereas Mn2O7 is acidic. This iss an easy concept of redox. Mn2o7 , Mn is in highest oxidation state +7 hence it cannot be oxidized more but it can reduce itself hencenut it gains electrons hence we can say it is accepting wlectrons or pair of electrons hence it works as lewis acid In Mn2o3 it is in +3 oxidation state and it. 31.
