Question

The equivalent conductivity of 0.1 M weak acid is 100 times less than that at infinite dilution. The degree of dissociation is

• A. 100
• B. 10
• C. 0.01
• D. 0.001

Answer 1

Answer: (C)

0.01

Answer 2

$\alpha = \frac{\Lambda_{m}^{c}}{\Lambda^{0}} = \frac{x/100}{x} = \frac{1}{100} = 0.01.$
