Which of the following happens when NaCl dissolves in water?
A) The chloride ions attract the negative poles of water molecules.
B) Sodium and chloride ions form covalent bonds with water molecules.
C) The sodium ions attract the negative poles of water molecules.
D) The sodium ions attract the positive poles of water molecules.

Question

Quizplus · Accepted Answer

When NaCl dissolves in water, the polar water molecules surround the ions of NaCl. The positively charged sodium ions (Na+) are attracted to the negative poles of the water molecules, while the negatively charged chloride ions (Cl-) are attracted to the positive poles of the water molecules. Therefore, option C is the correct answer. Option A is incorrect because the chloride ions are attracted to the positive poles of the water molecules. Option B is incorrect because covalent bonds are not formed between water molecules and ions. Option D is incorrect because the sodium ions are attracted to the negative poles of the water molecules.
