A balanced equation for the dissociation of KI

The balanced equation for the dissociation of KI is

KI → K⁺ + I⁻

Explanation:

KI is the potassium iodide.

K⁺ comes from the KOH, a strong base, so the cation is the conjugate weak acid and in water it does not react.

I⁻ comes from HI, a strong acid, so the anion is the conjugate weak base and in water it does not react.

K⁻ + H₂O ← KOH + H⁺

I⁻ + H₂O ← HI + OH⁻

That's why the arrow in the reaction is in the opposite direction.
