Question

Quizplus · Accepted Answer

In the spontaneous redox reaction, Cr is being oxidized from 0 to +3, while HCl is being reduced from +1 to 0 (elemental H₂ has an oxidation state of 0). Therefore, the substance that is the strongest oxidizing agent must be the one that is being reduced in the reaction, in this case, HCl.
