Question

Which of the following is an oxidation-reduction reaction? Which of the following is an oxidation-reduction reaction? Mg(s) + 2 HCl(aq) → MgCl2(aq) + H2(g) HCl(aq) + LiOH(aq) → LiCl(aq) + H2O(l) NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq) Pb(C2H3O2)2(aq) + 2 NaCl(aq) → PbCl2(s) + 2 NaC2H3O2(aq) All of the above are oxidation-reduction reactions.

Answer 1

NONE OF THE ABOVE

Step-by-step explanation:

None of the above are examples of an oxidation - reduction or a redox reaction . This is because there is no change in the oxidation state of any of the elements in the reaction when the reaction happens .

• For a redox reaction , transfer of electrons must take place.
• The oxidation states must increase or decrease in atleast 2 of the elements of a compound.
• For example :

`Zn^(2+)+Cu`⇒
`Cu^(2+)+Zn`
