Water can dissolve more substances than any other liquid because
Show answer
Answer: A. Water molecules are polar (dipolar): one end is slightly positive and the other slightly negative. This lets water attract and surround many ions and polar molecules, so it dissolves more substances than any other liquid.
Watch for: High specific heat is a true property of water but explains heat storage, not dissolving.
Why the other options are wrong
- B. Wrong because heat conduction does not explain dissolving power.
- C. Wrong because specific heat does not explain dissolving power.
- D. Wrong because being an oxide of hydrogen is not the reason.
