The equivalent conductivity of 0.1 M weak acid is 100 times lesser than that at infinite dilution. The degree of dissociation of weak electrolyte at 0.1 M is -
Options
- A100
- B10
- C0.01
- D0.001
Correct answer
C. 0.01
Step-by-step solution
The equivalent conductivity of 0.1 M weak acid is 100 times lesser than that at infinite dilution. ∧ v = ∧ 0 100 ∴ Degree of dissociation α = ∧ v ∧ 0 = ∧ 0 100 ∧ 0 = 0.01
