A hydrated potassium ion is surrounded by a shell of water molecules oriented primarily with their oxygen atoms toward the potassium ion.

Question

Quizplus · Accepted Answer

This statement is true. Potassium ion (K+) is a positively charged ion, which attracts the negatively charged oxygen atoms of water molecules. Therefore, a hydrated potassium ion is surrounded by a shell of water molecules with their oxygen atoms facing the ion. This orientation of water molecules around ions is known as solvation.
