question 21

Multiple Choice

Write a balanced half-reaction for the reduction of CrO₄^2-(aq) to Cr(OH) ₃(s) in a basic solution.

• A) CrO₄^2-(aq)+ 3 OH^-(aq)+ 3 e^- → Cr(O
• H)₃(s)+ 2 O₂(g)
• B) CrO₄^2-(aq)+ 3 H⁺(aq)+ 3 e^- → Cr(O
• H)₃(s)
• C) CrO₄^2-(aq)+ 3 H⁺(aq)→ Cr(O
• H)₃(s)+ 2 e^-
• D) CrO₄^2-(aq)+ 4 H₂O( )+ 3 e^- → Cr(O
• H)₃(s)+ 5 OH^-(aq)
• E) CrO₄^2-(aq)+ 3 OH^-(aq)→ Cr(O
• H)₃(s)+ 2 O₂(g)
