**Step 1. **Calculate the **initial amounts**.

**molarity (volume) → moles**

Recall:

$\mathbf{M}\mathbf{=}\frac{\mathbf{mol}}{\mathbf{L}}$

• **10****0 mL of 0.200 M CH _{3}COOH**

$\mathbf{moles}\mathbf{}{\mathbf{CH}}_{\mathbf{3}}\mathbf{COOH}\mathbf{=}\left(\mathbf{100}\overline{)\mathbf{}\mathbf{mL}}\mathbf{\times}\frac{{\mathbf{10}}^{\mathbf{-}\mathbf{3}}\overline{)\mathbf{}\mathbf{L}}}{\mathbf{1}\mathbf{}\overline{)\mathbf{mL}}}\right)\mathbf{\times}\frac{\mathbf{0}\mathbf{.}\mathbf{200}\mathbf{}\mathbf{mol}\mathbf{}{\mathbf{CH}}_{\mathbf{3}}\mathbf{COOH}}{\overline{)\mathbf{L}}}$

**moles CH _{3}COOH = 0.02 mol**

Consider the titration of 100.0 mL of 0.200 M acetic acid (Ka = 1.8 x 10 ^{-5}) by 0.100 M KOH. Calculate the pH of the resulting solution after the following volumes of KOH have been added.

b. 50.0 mL
