What is the net ionic equation for the oxidation of Fe²⁺ ions to Fe³⁺ ions in the presence of Cr2O72- ions in acidic medium?

Options

  1. A6Fe2+(aq) +Cr2O72-(aq) → 6 Fe³⁺(aq) + 2Cr3+(aq) + 7H2O(l)
  2. B6Fe2+(aq) +Cr2O72-(aq) + 14H+(aq) → 6Fe3+(aq) + 2Cr3+(aq) + 7H2O(l)
  3. CFe²⁺(aq) +Cr2O72-(aq) → Fe³⁺(aq) + Cr³⁺(aq)
  4. DFe²⁺(aq) +Cr2O72-(aq) + 6e- →Fe³⁺(aq) + 2Cr3+(aq) + 7H2O(l)

Correct answer

B. 6Fe2+(aq) +Cr2O72-(aq) + 14H+(aq) → 6Fe3+(aq) + 2Cr3+(aq) + 7H2O(l)

Step-by-step solution

This is the net ionic equation provided in the passage.
