What is the ionic equation for the reaction of potassium dichromate with H 2 S

Options

  1. ACr 2 O 7 2- + 3S 2- → 2CrO 4 2- + 2H + + S² -
  2. BCr 2 O 7 2- + 3S 2- → S + 2CrO 3 + H 2 O
  3. CCr 2 O 7 2- + 3H 2 S + 8H + → 2Cr³⁺ + 7H 2 O + 3S
  4. DCr 2 O 7 2- + 3S 2- → SO 4 2- + 2Cr³⁺ + 2H 2 O

Correct answer

C. Cr 2 O 7 2- + 3H 2 S + 8H + → 2Cr³⁺ + 7H 2 O + 3S

Step-by-step solution

Correct Option is : (C) Cr 2 O 7 2- + 3H 2 S + 8H + → 2Cr³⁺ + 7H 2 O + 3S
