When NaCl is added to body fluids, it results in the addition of
A) one solute particle per NaCl molecule and exerts an osmotic pressure equivalent to that of a nonelectrolyte.
B) two solute particles per NaCl molecule and exerts twice the osmotic pressure of the same number of nonelectrolyte molecules.
C) three solute particles per NaCl molecule and exerts one-third the osmotic pressure of the same number of nonelectrolyte molecules.
D) one solute particle per NaCl molecule, but because it is uncharged it does not result in osmotic pressure.

Question

Quizplus · Accepted Answer

When NaCl dissolves in body fluids, it dissociates into two ions: Na+ and Cl-. This results in two solute particles per NaCl molecule, which exerts twice the osmotic pressure compared to the same number of nonelectrolyte molecules.
