Question

complete the following reaction I- + H2O + O3​

Answer 1

Answer:

3OH) - + I2 + O2 balance now both sides

Answer 2

The completed reaction is:

I⁻ + O₃ + H₂O → I₂ + O₂ + OH⁻

I⁻ is the iodide ion and O₃ is ozone gas.

When I⁻ is reacted with ozone gas (O₃) in the presence of water molecules (H₂O), the ozone molecule oxidise the iodide ion to iodine and itself reduces to OH⁻ and forming  O₂.

In I⁻, the oxidation state of iodine is -1 and in the product state of I₂, the oxidation state is 0. This is oxidation.

In O₃, the oxidation state of O is 0 and in OH⁻, the oxidation state of O is -2. This is reduction.

This is an example of oxidation reduction reaction.

I⁻ + O₃ + H₂O → I₂ + O₂ + OH⁻
