Question

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

Answer 1

The correct answer is D. Are polar.

Step-by-step explanation:

When NaCl is dissolved in water it dissociates and each part of the molecule is surrounded by the water in the correct dipole. 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.
