Question

Balanced ionic equation for the reaction of Potassium Dichromate (VI) K2Cr2O7 with Sodium Sulphite Na2SO3 in acid solution to give Chromium (III) ion and sulphate ion is


  1. Cr2O7-2(aq) + 3SO32-(aq) + 8H+(aq) → 2Cr3+(aq) + 5SO42-(aq) + 4H2O(liq)

  2. Cr2O7-2(aq) + 3SO32-(aq) + 8H+(aq) → 2Cr3+(aq) + 3SO42-(aq) + 4H2O(liq)

  3. Cr2O7-2(aq) + 3SO32-(aq) + 5H+(aq) → 2Cr3+(aq) + 3SO42-(aq) + 4H2O(liq)

  4. Cr2O7-2(aq) + 2SO32-(aq) + 8H+(aq) → 2Cr3+(aq) + 3SO42-(aq) + 4H2O(liq)


Solution

The correct option is B

Cr2O7-2(aq) + 3SO32-(aq) + 8H+(aq) → 2Cr3+(aq) + 3SO42-(aq) + 4H2O(liq)


Cr2O7-2(aq) + 3SO32-(aq) + 8H+(aq) → 2Cr3+(aq) + 3SO42-(aq) + 4H2O(liq)
