How are the oxygen atoms balanced for redox equations in acidic solutions? A. H20 and OH- are used to balance the oxygen atoms.
B. H+ ions from the acid form H20 with the oxygen.
C. Ht and OH are used to balance the oxygen atoms.
D. H20 and H* are used to balance the oxygen atoms.

When balancing redox reaction equations, H20 and H^+ are used to balance the oxygen atoms.

Redox reaction equations show reactions in which electrons were lost or gained in the process. If the redox reaction involves oxygen, it is common to balance the oxygen atoms using H20 and H^+.

For instance, the equation of the reduction of MnO4^- to Mn^+ is shown below; MnO4^-(aq) + 8H^+(aq) + 5e > Mn^2+(aq) + 4H2O(l). We can see that hydrogen ions and water were used to balance the four oxygen atoms.

The answer is option D.

Explanation:

In balancing in acidic solutions, the oxygen is accounted for by adding a water molecule or H2O on the side that needs oxygen and 2H+ molecules for every H20 molecules placed on the other side of the equation.

The H+ and H2O molecules are in the ratio 2 : 1
