Chapter 16, Problem 16.4QE

Interpretation Introduction

Interpretation:

The titration of acetic acid (CH₃COOH) with sodium hydroxide (NaOH), both 0.100 M.  The titration curve has to be drawn and the regions at which the equilibrium is a strong acid or base, a weak acid or base, and a buffer have to be labeled.

Concept introduction:

Estimating the pH of Mixtures of Acids and Bases:

If $H_3{O}^{+}$ ion is present in the solution the pH of the solution is $\text{1}$. If ${\text{OH}}^{\text{-}}$ ion is present in the solution the pH of the solution is $\text{14}$.

If $H_3{O}^{+}$ ion concentration is equal to ${\text{OH}}^{\text{-}}$ concentration, the solution neutral and the pH of the solution is $7$.
