Chemistry - Ionic Equilibrium Question with Solution | TestHub

0.01 moles of a weak acid HA ( ${\mathrm{K}}_{\mathrm{a}}=2.0\times 10^{-6}$ ) is dissolved in 1.0 L of 0.1 M HCl solution. The degree of dissociation of HA is ' Y ' $\times 10^{-5}$. The value of ' Y ' is :

(Round off to the nearest integer)

[Neglect volume change on adding HA. Assume degree of dissociation < < 1]
