Question

A diatomic gas $X_2$ at $1	ext{ atm}$ is bubbled through an aqueous solution containing a mixture of $1	ext{ M } Y^-$ and $1	ext{ M } Z^-$ at $25^\circ	ext{C}$. If the standard reduction potentials of the corresponding non-metals follow the order $Z_2 > Y_2 > X_2$, which of the following describes the correct redox outcome?

Prashant Kotian · Accepted Answer

Correct answer: A. A halogen or non-metal with a higher standard reduction potential will spontaneously oxidize the anion of a non-metal with a lower reduction potential. Since the reduction potential of , can oxidize to . However, since , cannot oxidize .
