2 IO 3 - + xI - + 12 H + → 6 I 2 + 6 H 2 What is the value of x ?

Options

  1. A2
  2. B12
  3. C10
  4. D6

Correct answer

C. 10

Step-by-step solution

Assign the oxidation number to all the elements in the reaction, 2 I + 5 O 3 - + x I - - 1 + 12 H + + 1 → 6 I 2 0 + 6 H 2 O 2 IO 3 - + 10 e - → I 2 2 I - → I 2 + 2 e - × 5 2 IO 3 - + 10 I - + 12 H + → 6 I 2 + 6 H 2 O Therefore, the value of x = 10 in the reaction.
