Concept explainers
(a)
Interpretation: The given reactions of calcium compounds are to be validated for being redox reactions.
Concept introduction: The reaction in which reduction and oxidation process occurs simultaneously is termed as
In oxidation there is loss of electrons occur which increases the oxidation state of an atom whereas in reduction process there is gaining of electrons occur which decreases the oxidation state of an atom.
To determine: If the given reaction of calcium compound is a redox reaction or not.
(b)
To determine: If the given reaction of calcium compound is a redox reaction or not.
(c)
To determine: If the given reaction of calcium compound is a redox reaction or not.
(d)
To determine: If the given reaction of calcium compound is a redox reaction or not.
