The dissociation constant of acetic acid is 1.6 $\times 1 0^{- 5}$ . The degree of dissociation of 0.01 M acetic acid in the presence of 0.1 M HCl is equal to

Options:

Answer:

Solution:

For weak acid:
$α = \sqrt{\frac{Ka}{C}}$
$α = \sqrt{\frac{1 .6 × 10^{- 5}}{10^{- 2}}}$
$α = 4 \times 10^{- 2}$
