Question

How do you find the degree of ionization of the solutions when accounting for the dillution effect of adding 10 mL of water? Also for the second page, how do you calculate pH with a buffer using the Henderson-Hasselbalch equation?

Solution 2 - 10.0 mL of 0.1 M HC2H302 +10.0 mL H20 Measured pH_2.42 To determine the [H3O+], account for the dilution effect of adding 10.0 mL of water, and use MV1 = M2V2 Degree of lonization of solution 2 Solution 3 - 10.0 mL of 0.1 M HC2H302 + 90.0 mL of H20 Measured pH 2.59 To determine the [H3O*], account for the dilution effect of adding 90.0 mL of water, and use MiV1 = M2V2 Degree of lonization of solution 3 How does the dilution affect degree of ionization of acetic acid?
