Degree of dissociation =α=( Lambdac/ Lambda∞)=(50/250)=0.2

Q. The molar conductance of $0.001 M$ acetic acid is $50 o h m^{- 1} c m^{2} m o l^{- 1}$ . The maximum value of molar conductance of acetic acid is $250 o h m^{- 1} c m^{2} m o l^{- 1} .$ What is the degree of dissociation $(α)$ of acetic acid?

0.5

0.2

0.3

0.4

Degree of dissociation $= α = \frac{Λ _{c}}{Λ _{\infty}} = \frac{50}{250} = 0.2$
