They are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature.

Answer:
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.
