study figure 8-1. when the ionic compound KI is dissolved in water, the I- ions are pulled into the solution by the attraction between

A.the K+ and I- ions.

BThe K + ion and the negative end of the water molecule.

C.the I- ion and the negative end of a water molecule

DThe I- ion and the positive end of a water molecule

PLEASE HELP

Answer is: D. The I⁻ ion and the positive end of a water molecule.

Dissociation of potassium iodide in water:

KI(aq) → K⁺(aq) + I⁻(aq).

Solvation is the interaction of solvent (water) with molecules or ions (in this example K⁺ and I⁻) in a solute.


Anion I⁻ has negative charge, so positive end (hydrogen atoms) of a water molecul attracts them.

Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute.
