A certain weak acid, ha, has a ka value of 6.0*10-7. calculate the percent ionization of ha in a 0.10 m solution.

For the purpose, we will use the equation for determining the dissociation constant from concentration and percent of ionization:

Kd = c * α²

α = √ (Kd/c) * 100%

Kd = 6.0*10⁻⁷

c (HA) = 0.1M

α = √ (6.0*10⁻⁷/0.1) * 100% = 0.23%

So, in the solution, the acid percent of ionization will be just 0.23%.
