show all work please thank you!!
9. (4 pts) Trifluoroacetic acid (CF3CO2H; pk, = 0.23) and acetic acid (CH3CO2H; pka = 4.75) are monoprotic acids (meaning they can dissociate only one H+ ion/molecule of acid). Using your knowledge of structure, explain why the acid dissociation (Ka) of acetic acid is greater than that for trifluoroacetic acid. Place your answer in the space provided. indisht n.....
Acetic acid (CH3COOH) and trifluoroacetic acid (CF3COOH) are shown by these particulate models.
Acetic acid (CH3COOH) and trifluoroacetic acid (CF3COOH) are shown by these particulate models. The K, for trifluoroacetic acid is 104times greater than acetic acid. Use the models to account for the differences in magnitude for the K, constant. The yellow atoms are fluorine, the red atoms are oxygen, the black atoms are carbon, and the white atoms are hydrogen. Part 1Write the formulas for the conjugate bases for the two structures The conjugate base of acetic acidThe conjugate base of trifluoroacetic acid Part...

Calculate the total amount of acetric acid needed. Calculate the radio of the two form of that will when the pH is 5.1 Use this ratio to calculate the % of calculate that will be in the A form. Assume that each NaOH will convert one. Use this plus the...
