In the reaction shown below, oxidation state of the carbon in reactant and product are (i) and (ii) respectively ? Is the given reaction a redox reaction?
`Na_(2)CO_(3)(aq)+HCl (aq) to Na^(o+)(aq)+Cl^(-) (aq)+H_(2)O(l)+CO_(2)(g)`

Options

A. (i) 6, (ii) 4, yes
B. (i) 6, (ii) 6, no
C. (i) 4, (ii) 4, No
D. 4, (ii) 4, yes

Answer

C

Explanation

The redox reaction involve loss or gain of electron(s) i.e., change in oxidation state. Given reaction is not a redox reaction as this reaction involves no change in oxidation state of reactant of product.
