Question

What overall reaction consists of the following elementary steps?

CIO⁻(aq) + H₂O(1) - HCIO(aq) + OH⁻ (aq)
I⁻ (aq) + HCIO(aq) → HIO(aq) + Cl⁻(aq)
OH⁻(aq) + HIO(aq) - H₂O(1) + IO⁻(aq)

Answer 1

The overall reaction resulting from the combination of the given elementary steps is CIO−(aq) + I−(aq) → Cl−(aq) + IO−(aq).

Step-by-step explanation:

Overall Reaction from Elementary Steps

To find the overall reaction from given elementary steps, you need to combine them while cancelling out any species that appear on both sides of the equations (as they act as intermediates in the sequence of elementary steps). After careful analysis, the overall reaction can be deduced as follows:

1. 
   
3. CIO−(aq) + H2O(l) → HCIO(aq) + OH−(aq)
4. 
   
6. I−(aq) + HCIO(aq) → HIO(aq) + Cl−(aq)
7. 
   
9. OH−(aq) + HIO(aq) → H2O(l) + IO−(aq)

By adding these up and cancelling out the HCIO(aq) and HIO(aq), which appear on both the reactant and the product sides, along with water molecules that also appear on both sides, we get:

CIO−(aq) + I−(aq) → Cl−(aq) + IO−(aq)

The overall reaction consists of ClO− and I− reacting to form Cl− and IO−.
