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.
