Which of the following is not an oxidation-reduction reaction?

A. XeF6(s) → XeF4(s) + F2(g)
B. 2Cs(s) + L2(g) → 2Csl(s)
C. 2H2SO4(aq) + 2Ba(oh)2(aq) → 2BaSO4(s) + 4H2O(I)
D. Zn(s) + 2AgNo3(aq) → Zn(NO3)2(aq) + Ag(s)

Answer : The option (C) is not an oxidation-reduction reaction.

Explanation :

A : $XeF_6(s)\righatrrow XeF_4(s)+F_2(g)$

This is an oxidation-reduction reaction. In this reaction, the oxidation state of 'Xe' changes from (+6) to (+4) and the oxidation state of 'F
' changes from (-1) to (0). That means 'Xe' shows reduction and 'F' shows oxidation in the reaction.

B : $2Cs(s)+I_2(g)\righatrrow 2Csl(s)$

This is an oxidation-reduction reaction. In this reaction, the oxidation state of 'Cs' changes from (0) to (+1) and the oxidation state of 'I' changes from (0) to (-1). That means 'I' shows reduction and 'Cs' shows oxidation in the reaction.

D : $Zn(s)+2AgNo_3(aq)\rightarrow Zn(NO_3)_2(aq)+Ag(s)$

This is an oxidation-reduction reaction. In this reaction, the oxidation state of 'Zn' changes from (0) to (+2) and the oxidation state of 'Ag' changes from (+1) to (0). That means 'Ag' shows reduction and 'Zn' shows oxidation in the reaction.

C : $2H_2SO_4(aq)+2Ba(OH)_2(aq)\rightarrow 2BaSO_4(s)+4H_2O(I)$

This is not an oxidation-reduction reaction. In this reaction, the oxidation states are not changes.

Hence, the option (C) is not an oxidation-reduction reaction.
