(a)
Interpretation:
The oxidation state of each element in potassium carbonate
Concept introduction:
Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.
Oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.
(b)
Interpretation:
The oxidation state of each element in ammonium ion
Concept introduction:
Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.
Oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.
(c)
Interpretation:
The oxidation state of each element in calcium phosphide
Concept introduction:
Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.
Oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.
(d)
The oxidation state of each element in sulfur tetrachloride
Concept introduction:
Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.
Oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.
