During an electrolysis experiment, the following species are present in solution: H+, CH3COOH, CH3COO-, Na+, SO42-, H2O. The lead electrode dipped in the solution serves as the anode. Theoretically H2O, and Pb (s) are species that can be oxidized. Why is only Pb (s) oxidized during this experiment?     because only solids can be oxidized     because experimentally water can only be reduced     because Pb (s) is a stronger oxidizing agent than water     because Pb (s) is a stronger reducing agent than water

During an electrolysis experiment, the following species are present in solution: H+, CH3COOH, CH3COO-, Na+, SO42-, H2O. The lead electrode dipped in the solution serves as the anode.

Theoretically H2O, and Pb (s) are species that can be oxidized. Why is only Pb (s) oxidized during this experiment?

   

because only solids can be oxidized

   

because experimentally water can only be reduced

   

because Pb (s) is a stronger oxidizing agent than water

   

because Pb (s) is a stronger reducing agent than water
