Which weak acid solution has the greatest percent ionization? which weak acid solution has the greatest percent ionization? 0.140 m h2c6h6o6 0.700 m h2c6h6o6 0.0140 m h2c6h6o6?

0.0140 M H₂C₆H₆O₆.

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.
