Concept explainers
a)
Interpretation:
The oxidation state of oxygen in each oxide and the oxidation state of the other element has to be identified.
Concept introduction:
Oxidation state:
As per the IUPAC definition, the charge of the atom is the oxidation state of an atom after ionic approximation of its heteronuclear bonds or it is a number assigned to an atom or an element which represents the number of electrons lost or gained.
b)
Interpretation:
The bonding nature of metal oxides has to be identified.
Concept introduction:
Covalent bond:
The bond which involves sharing of electrons between the atoms present in the molecule
Ionic bond:
The bond which involves transfer of electrons between the atoms present in the molecule
c)
Interpretation:
The acidic or basic nature of the oxides has to be identified.
Concept introduction:
Acid:
The substance which is capable of accepting a pair of nonbonding electrons and forms covalent bond
Base:
The substance which is capable of donating a pair of nonbonding electrons
d)
Interpretation:
The identity of the metal in the compounds (1) and (2) has to be identified.
Concept introduction:
Oxidation state:
As per the IUPAC definition, the charge of the atom is the oxidation state of an atom after ionic approximation of its heteronuclear bonds or it is a number assigned to an atom or an element which represents the number of electrons lost or gained.
