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:

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.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
