Accepted Answer
The balanced ionic equation for the reaction between potassium dichromate (K₂Cr₂O₇) and iron(II) chloride (FeCl₂) in acidic solution is:
Cr₂O₇²⁻(aq) + 6Fe²⁺(aq) + 14H⁺(aq) → 2Cr³⁺(aq) + 6Fe³⁺(aq) + 7H₂O(l)
This reaction involves the oxidation of iron(II) ions (Fe²⁺) to iron(III) ions (Fe³⁺) by dichromate ions (Cr₂O₇²⁻), which are reduced to chromium(III) ions (Cr³⁺).
