Question

составить окислительно-восстановительное уравнениеNaI+NaIO3+H2SO4=I2+Na2SO4+H2O...пожалуйста помогите решить!!!!!!!!

Answer 1

5NaI +  NaIO₃ + 3H₂SO₄ = 3I₂+3Na₂SO₄+3H₂O

І⁻- 1е = I⁰     |5   ок-е

I⁺⁵ + 5е = I⁰ |1   в-е

І⁻- в-ль,

I⁺⁵ -  ок-ль

Answer 2

Balancing the Chemical Equation

To balance the chemical equation for the reaction between NaI, NaIO3, and H2SO4 to produce I2, Na2SO4, and H2O, we can follow these steps:

1. Write down the unbalanced equation: NaI + NaIO3 + H2SO4 = I2 + Na2SO4 + H2O

2. Identify the elements present on both sides of the equation: - Sodium (Na) - Iodine (I) - Sulfur (S) - Oxygen (O) - Hydrogen (H)

3. Balance the elements one at a time: - Start by balancing the elements that appear in only one compound on each side of the equation.

4. Balance the equation: - After balancing the elements, the balanced chemical equation is:

5NaI + NaIO3 + 6H2SO4 = 3I2 + 3Na2SO4 + 6H2O

This balanced equation ensures that the same number of each type of atom is present on both sides of the equation.
