Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Cl⁻ ions
  2. Na⁺ ions
  3. Na⁺ and Cl⁻ ions
  4. H₂O molecules

Correct answer and explanation

Correct answer: H₂O molecules

Explanation: ✅ Correct Answer: D) H₂O molecules 📚 Explanation: When common salt (NaCl) is dissolved in water, the sodium (Na+) and chloride (Cl-) ions are pulled apart by the water molecules. Each positive sodium ion becomes surrounded by the negative oxygen ends of the water molecules. This process is called hydration and it keeps the ions from recombining. This is the basic reason why salt dissolves so easily in water to form a uniform solution.
