(a)
Interpretation: Whether the given reaction,
Concept Introduction: The reaction that involves the oxidation and reduction process is a redox reaction. Oxidation involves the loss of electrons while reduction involves a gain of electrons.
(a)
Answer to Problem 58A
The given reaction is a redox reaction since it involves both the oxidation and reduction processes.
Explanation of Solution
The given reaction,
It involves the oxidation of
Oxidation:
Reduction:
So, it involves both oxidation and reduction processes it is a redox reaction.
(b)
Interpretation: Whether the given reaction,
Concept Introduction: The reaction that involves the oxidation and reduction process is a redox reaction. Oxidation involves the loss of electrons while reduction involves a gain of electrons.
(b)
Answer to Problem 58A
The given reaction is not a redox reaction since it doesn't involve oxidation and reduction processes.
Explanation of Solution
The given reaction,
It doesn't involve any change in oxidation number. The oxidation state of Cr is +3 on the reactant and product side. So, it is not a redox reaction.
(c)
Interpretation: Whether the given reaction,
Concept Introduction: The reaction that involves the oxidation and reduction process is a redox reaction. Oxidation involves the loss of electrons while reduction involves a gain of electrons.
(c)
Answer to Problem 58A
The given reaction is not a redox reaction since it doesn't involve oxidation and reduction processes.
Explanation of Solution
The given reaction,
It doesn't involve any change in oxidation number. The oxidation state of B is +3 on the reactant and product side. So it is not a redox reaction.
