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.
Explanation:
The three types of consumers in the animal kingdom are carnivores, herbivores and omnivores. Carnivores eat only meat. Herbivores eat only plants, while omnivores need to consume both plants and meat to satisfy their dietary requirements.
