Which of the following is not an oxidation reduction reaction a) xef6(> xef4(s)+f2(g) b) 2cs(s)+i2(> 2csl(s) c) 2h2so4(aq)+ 2ba(oh)2(> 2baso4(s)+4h2o(i) d) zn(s)+> zn(no3)2(aq)+ag(s)

C) 2H2SO4(aq)+ 2Ba(OH)2(aq)>2BaSO4(s)+4H2O(I)

Explanation:

The reaction proper:

     2H₂SO₄ + 2Ba(OH)₂ → 2BaSO₄ + 4H₂O

The above reactions is a typical acid-base neutralization reaction.

A reaction in which oxidation-reduction did not take place is called a non-redox reaction. In such a reaction, there is no transfer of electrons between reactants, that is, none of the atoms of the reactants changes its oxidation number in forming the products.

   Most neutralization reactions are non-redox reactions.
