Question

For the reaction Sb₂S₃ + 6HCl → 2SbCl₃ + 3H₂S, which species undergoes reduction?

Choose one · Correct answer highlighted

None of these Correct Sb₂S₃ HCl SbCl₃

Reduction is electron gain. Sb (+3 in Sb₂S₃) remains +3 in SbCl₃, but S (-2 to -2) doesn’t change; no reduction occurs here—it’s not redox.
