The hydrogen ion concentration of $0.2 \mathrm{~N}$ $\mathrm{CH}_{3} \mathrm{COOH}$ which is $40 \%$ dissociated is
  1. $0.08 \mathrm{~N}$
  2. $0.12 \mathrm{~N}$
  3. $0.80 \mathrm{~N}$
  4. $1.2 \mathrm{~N}$

Solution

$\left[\mathrm{H}^{+}ight]=\mathrm{C} \alpha=0.2 \times 0.40=0.08 \mathrm{~N}$
$$
\left(\alpha=\frac{40}{100}=0.40ight)
$$ ,
