FREE Expert Solution

We have to determine which of the given reactions is a redox reaction.

Redox reactions are reactions where a change in oxidation states takes place.

The increase in oxidation state of an element is oxidation while a decrease in oxidation state is reduction.

We will look at the reactions individually and see if there is a change in the oxidation state of an element.

Which of the following is an oxidation-reduction reaction?

a. Cu(s) + 2AgNO3(aq) → 2Ag(s) + Cu(NO3)2(aq)

b. HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq)

c. AgNO3(aq) + HCl(aq) → AgCl(s) + HNO3(aq)

d. Ba(C2H3O2)2(aq) + Na2SO4(aq) → BaSO4(s) + 2NaC2H3O2(aq)

e. H2CO3(aq) + Ca(NO3)2(aq) → 2HNO3(aq) + CaCO3(s)
