Chemistry - Electrochemistry Question with Solution | TestHub

The degree of dissociation $\alpha$ is given by the ratio of molar conductivity at a given concentration to the molar conductivity at infinite dilution.

$\alpha =\frac{{\Lambda }_m}{{\Lambda }_m^{\infty }}$

Substituting the given values:

$\alpha =\frac{3.3}{132}=0.025$

Percentage dissociation $=\alpha \times 100$

Percentage dissociation $=0.025\times 100=2.5\%$

Answer: $2.5\%$
