Sodium chloride (naci) dissolves in water because water molecules
a. lose electrons
b. have a ph near 7
c. have a high specific heat
d. are polar

The correct answer is D. Are polar.

Explanation:

Na (+) is surrounded by the oxygen part of water, without it dissolving itself, and Cl (-) is surrounded by the hydrogens. NaCl is a salt and therefore it dissociates when in contact with water.
