Use le chatelier's principle to explain why the solubility of iodine in water increases as the concentrations of potassium iodide increases

The theory,depends on the various factors:-

According to the question, the molecule moves from high concentration to low concentration in different volumes and Pressure.

Then, increasing the concentration of the iodide ions creates a disturbance. According to theory, the system will react in a way that tends to reduce the disturbance.

The reaction shift in the forward direction, to make more triiodide ions and consume some of the added iodides with aqueous iodine. This causes more solid iodine to dissolve in the solution (increasing concentration).

Reaction: I₂(aq) + I⁻ (aq) ⇄ I₃⁻(aq).

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

a electronegativity decreases beacuse the size of nucleus is bigger.
