Complete and balance the following redox equation using the set of smallest whole numbers coefficients. What is the sum of the coefficients? HI + HNO₃ → I₂ + NO (acidic solution)

Question

Quizplus · Accepted Answer

The balanced redox equation is: 2HI + 2HNO3 → I2 + 2NO + 2H2O. The sum of the coefficients is 2 + 2 + 1 + 2 + 2 = 9. However, the correct balanced equation considering the smallest whole numbers is: 2HI + 2HNO3 → I2 + 2NO + 4H2O, which gives a sum of coefficients as 2 + 2 + 1 + 2 + 4 = 11. But the correct balanced equation with the smallest whole numbers is: 6HI + 2HNO3 → 3I2 + 2NO + 4H2O, which gives a sum of coefficients as 6 + 2 + 3 + 2 + 4 = 17.
