Concept explainers
(a)
Interpretation: The oxidized and reduced elements in the given reaction should be identified.
Concept introduction:
Change in the oxidation number of atoms involved in the reaction is one of the special characteristic of reduction reaction.
The number of electrons an atom tends to give up or gain in a chemical reaction is called oxidation number.
Oxidation: Losing electrons, increasing oxidation number.
Reduction: Gaining electron, decreasing oxidation number.
Oxidizing agent is a substance that removes electrons from another reactant in a chemical reaction and so it is reduced by taking electron onto itself and the reactant is oxidized by having its electron taken away.
Reducing agent is the element or compound in a redox reaction that donate an electron to another species and so it is oxidized.
(b)
Interpretation: The oxidized and reduced elements in the given reaction should be identified.
Concept introduction:
Oxidation-reduction reaction: Both the oxidation and reduction reaction occurs together in a chemical reaction. It is also known as redox reaction.
