Question

Which of these best explains why the hydrogen atoms in a water molecule are attracted to Cl− ions in sodium chloride (NaCl)?

Answer 1

Answer:

C. The hydrogen atoms have partial positive charges

Hopefully this helps! :)

Answer 2

Answer: C. The hydrogen atoms have partial positive charges.

Explanation: The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

Water being polar in nature dissolves $NaCl$ by getting between the oppositely charged ions of solute and thus decreasing the forces of attraction between the ions. The positively charged $Na^+$ ions are attracted to positive pole of water which is hydrogen and the negatively charged $Cl^-$ is attracted to negative pole of water which is oxygen.
