Evaporation occurs on the surface of a substance
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.
The sum of the oxidation numbers of all atoms in a neutral compound is zero.
You can separate out the canola oil easily, because it has cooled down enough to turn back into a solid.
