What is the ionic equation for the reaction of potassium dichromate with iodide?

Options

  1. AK 2 Cr 2 O 7 + 2I - → 2K + + Cr 2 O 3 + I 2
  2. B2K 2 Cr 2 O 7 + 4I - → 4K + + 2Cr 2 O 3 + I 2
  3. CK 2 Cr 2 O 7 +14H + + 6I - → 2K + + 2Cr 3+ + 3I 2 + 7H 2 O
  4. DK 2 Cr 2 O 7 + 3I - → 2K + + 2CrO 4 2- + I 2

Correct answer

C. K 2 Cr 2 O 7 +14H + + 6I - → 2K + + 2Cr 3+ + 3I 2 + 7H 2 O

Step-by-step solution

Correct Option is : (C) K 2 Cr 2 O 7 +14H + + 6I - → 2K + + 2Cr 3+ + 3I 2 + 7H 2 O
