The following change occurs in acidic solution:
____ S^2-(aq) + ____ Cr₂O₇^2-(aq) → ____ S(s) + ____ Cr³⁺(aq)
In the balanced equation,for every mole of Cr₂O₇^2- that reacts,_____ mol of H⁺ are consumed.

Question

Quizplus · Accepted Answer

In acidic solutions, the dichromate ion (Cr2O7^2-) is reduced to Cr^3+, and sulfur is oxidized from S^2- to S. The balanced redox reaction requires 14 H+ ions for every mole of Cr2O7^2- to balance the hydrogen atoms and charge.
