Calculate dissociation constant for an acid $\text{HA}$ having $\left[{\mathrm{H}}^{+}\right]$ equals to $\text{0}\text{.1}\text{M}$ (Given: degree of dissociation of $\text{HA}$ is $\text{1\%}$)

• A

  $\text{1}{\text{0}}^{\text{-8}}$
• B

  $\text{1}{\text{0}}^{\text{-6}}$
• Correct answer
  C

  $\text{1}{\text{0}}^{\text{-3}}$
• D

  $\text{1}{\text{0}}^{\text{-7}}$

Hence, the correct answer is option: 'C'.
