Chapter 16.1, Problem 3RQ

Interpretation Introduction

Interpretation:

The molecular-level view of an aqueous solution of the strong acid HClhas to be drawn.

Concept Introduction:

All strong acids are strong electrolytes. They completely dissociate to give ${\mathrm{H}}^{+}$ ionsin the aqueous solution.

Explanation of Solution

HCl is a strong acid. It completely dissociates to give ${\mathrm{H}}^{+}$ ion and ${\text{Cl}}^{-}$ ion in the solution.No HCl molecules will remain in the solution. HCl molecules dissociate in an aqueous solution to give ${\text{H}}^{+}$ ion and ${\text{Cl}}^{-}$ ion.

  $\mathrm{HCl}\to {\mathrm{H}}^{+}+\mathrm{C}{\mathrm{l}}^{-}$

This is a molecular-level view of an aqueous solution of the strong acid HCl.
