Here's how to write the net ionic equation for the reaction between hydrobromic acid (HBr) and potassium hydroxide (KOH):

1. Write the balanced molecular equation:

HBr(aq) + KOH(aq) → KBr(aq) + H₂O(l)

2. Write the complete ionic equation:

H⁺(aq) + Br⁻(aq) + K⁺(aq) + OH⁻(aq) → K⁺(aq) + Br⁻(aq) + H₂O(l)

3. Identify and cancel spectator ions:

* Spectator ions are those that appear on both sides of the equation unchanged. In this case, K⁺ and Br⁻ are spectator ions.

4. Write the net ionic equation:

H⁺(aq) + OH⁻(aq) → H₂O(l)

Therefore, the net ionic equation for the reaction between hydrobromic acid and potassium hydroxide is: H⁺(aq) + OH⁻(aq) → H₂O(l)
