Problem

When solid NaCl dissolves completely in liquid water, which of the following statements best describes the resulting mixture at the particulate level? a) Neutral

\text{NaCl}

formula units remain intact and are dispersed uniformly among water molecules. b) Water reacts with

\text{NaCl}

to form

\text{NaOH}

and

\text{HCl}

, which then dissolve as separate molecules. c) Individual

\text{Na}^+

and

\text{Cl}^-

ions become separated from one another, each surrounded by oriented water molecules that stabilize their charges. d)

\text{Na}^+

and

\text{Cl}^-

ions stay paired together as

\text{NaCl(aq)}

units with minimal interaction with surrounding water.
