How does `Cu_(2)O` act as both oxidant and reductant ?

Text Solution

Verified by Experts

`Cu^(+)` undergoes disproportionation to form `Cu^(2+)` and Cu.
`" "2Cu^(+)(aq) rarr Cu^(2+)(aq)+Cu(s)`
Thus, `Cu^(+) " or " Cu_(2)O` acts both as an oxidant and a reductant.

In the chemical change aN_(2)H_(4)+bBrO_(3)^(-)toaN_(2)+bBr^(-)+6H_(2)O , answer the following questions: The species acting as oxidant and reductant respectively are:

The oxidation number of an element in a compound decides its nature to acts as oxidant or reductant. Oxidation number is defined and the residual charge which an atom has or appears to have in a molecule whenal other atoms are removed from the molecule as ions. Oxidation number is frequently used interchangebly with oxidation state. The stock notations of oxidation number are based on the periodic property-electronegativity. An atom in a molecule can be assigned positive, negative or zero oxidation number by considering its environment. In few cases, oxidation number can evenn be fractional. Oxidation number of Y in YBa_(2)Cu_(2)O_(7) is +3, then oxidation number of Cu is:

Redox is a reaction in which both oxidation and reduction will take place simultaneously . It is obvious that if one substance gives electron there must be another substance to accept these electrons . In some reactions, same substance is reduced as well as oxidised, these reactions are termed as disproportionation reactions. For calculating equivalent mass in redox reaction change in oxidtaion number is realted to n-factor which is reciprocal of molar ratio. The equivalent weight of Cu_(2)S in the following reaction is Cu_(2)S + O_(2) to Cu^(+2) + SO_(3)
