Bromine displaces iodine from a solution if potassium iodide.
Q:Write the balanced half-equation for this reaction .
I have solved it but I m not sure that it is right.My answer is 2Br- ------$ Br2 +2e-
2I- +2e- --------I2+
The ionic equation is 2Br- + 2I- ------$Br2 +I2
Question related to half equation.?

Reduction half equation: Br₂(aq) + 2e⁻ → 2Br⁻(aq)
Oxidation half equation: 2I⁻(aq) → I₂(aq) + 2e⁻
Overall equation: Br₂(aq) + 2I⁻(aq) → 2Br⁻(aq) + I₂(aq)
Oxidation half equation: 2I⁻(aq) → I₂(aq) + 2e⁻
Overall equation: Br₂(aq) + 2I⁻(aq) → 2Br⁻(aq) + I₂(aq)
