Answer:
0.0140 M H₂C₆H₆O₆.
Step-by-step explanation:
- We should mention the relation: Ka = α²C,
Where, Ka is the dissociation constant of the acid.
α is the degree of ionization of the acid.
C is the concentration if the acid.
The percent of ionization (α %) = α x 100.
α = √Ka/C
∴ α is inversely proportional to the concentration of the acid.
So, the acid with the lowest concentration has the greatest percent ionization.
