Question

Which statement about the following redox reaction in acidic solution is not correct?

H2S(aq) + Cr2O72(aq) S(s) + Cr3+(aq)

The oxidation state for sulfur goes from 2 0. The oxidation state for Cr goes from +6 +3. You need to write a “2” in front of the Cr+ molecule on the right side to balance the redox atoms. The sulfur atom loses two electrons and the Cr atom gains three electrons in this event. The final step involves adding oxygen atoms to the left side of the reaction and hydrogen atoms to the right side of the reaction.
