Answer :
Final answer:
The degree of dissociation of HA can be calculated using the formula α = √(k * C), where α is the degree of dissociation, k is the specific conductivity, and C is the concentration of the electrolyte. Given the specific conductivity of HA as 5 x 10^-5 S cm–1 and the concentration as 0.001 M, the degree of dissociation is 0.5. The correct option is d.
Explanation:
The degree of dissociation of a weak electrolyte can be calculated using the formula:
α = √(k* C)
Where α is the degree of dissociation, k is the specific conductivity, and C is the concentration of the electrolyte.
Given the specific conductivity of HA as 5 x 10^-5 S cm–1 and the concentration as 0.001 M, we can substitute the values into the formula to solve for α:
α = √((5 x 10^-5) * 0.001)
= 0.005
Therefore, the degree of dissociation of HA is 0.005, which is equal to 0.5.
