Chapter 8: Problem 24

The saline solution used to soak contact lenses is primarily NaCl dissolved in water. Which of the following ways to represent the solution is not correct? $$\begin{array}{l}{\text { a. } \operatorname{NaCl}(a q)} \\ {\text { b. } \mathrm{NaCl}(s)} \\ {\text { c. } \mathrm{Na}^{+}(a q)+\mathrm{Cl}^{-}(a q)}\end{array}$$

Short Answer

Expert verified
The incorrect representation of the saline solution is NaCl(s).

Step by step solution

01

Understanding the meanings of the notations

NaCl(aq) indicates that the sodium chloride is dissolved in water which is correct for a saline solution. Na+(aq) + Cl-(aq) means sodium and chloride ions are dissolved in water as separate ions, which is also correct as NaCl dissociates into its ions when it dissolves in water. NaCl(s) means the sodium chloride is in a solid state, which is incorrect because the question states that the sodium chloride is dissolved in a saline solution, not in a solid form.
02

Determining the incorrect representation

From the above explanation, we can see the NaCl(s), which represents the sodium chloride in a solid state, is the incorrect representation for a sodium chloride solution.
