Question

Question: List the following substances in order of their increasing oxidizing power: (a) acetoacetate, (b) cytochrome b $\left(F{e}^{3+}\right)$, (c) $NA{D}^{+}$, (d) $S{O_4}^{2-}$ , and (e) pyruvate.

Short answer

The order is: $S{O_4}^{2-},acetoacetate,NA{D}^{+},pyruvate,cytochromeb\left(F{e}^{3+}\right)$

Step-by-step solution

Oxidation-Reduction Reaction

An oxidation-reduction reaction is a chemical process in which the oxidation number of an atom, ion, or molecule changes as a result of losing or gaining an electron.

Explanation

We need to look at the table of standard reduction potentials, which is on page 466 , in order to compare the oxidising power of various substances. The numbers for oxidation potential are opposite in sign from those for reduction potential in the table. The stronger an object's ability to oxidise, the more positive its reduction potential.

Hence, by increasing the oxidising power of the provided compounds, you can rank them as:
