Chapter 7.1, Problem 3CC

Summary Introduction

To determine:

Which compound gets oxidized and which one gets reduced in the given redox reaction ( ${\text{C}}_{\text{4}}{\text{H}}_{\text{6}}{\text{O}}_{\text{5}}\text{+}{\text{NAD}}^{\text{+}}\to {\text{C}}_{\text{4}}{\text{H}}_{\text{4}}{\text{O}}_{\text{5}}\text{+NADH}{\text{+H}}^{\text{+}}$).

Concept introduction:

In a redox reaction, the compound which gains hydrogen or electrons gets reduced (oxidizing agent) and the one that loses hydrogen or electrons gets oxidized (reducing agent).
