i just wanted to to check my work for the experimental ka of
acetic acid .
is my experimental ka correct?
Since the titration with l-mL increments is done to give a rough estimate of the point, you need report on only the results from the more precise increment titra ents is done to give a rough estimate of the equivalence Acetic Acid Literature value for K, of Acetic Acid 1.8 X 10 (p.) Literature value for pK, of Acetic...

in an experiment, 5.00 mL 0.100 M acetic acid (Ka = 1.75 x 10^-5 at 25 C) was titrated with 0.100 M NaOH solution. The system will attain this pH after 10.0 mL of the titrant has been added
6) The Ka of acetic acid (HC2H302) is 1.8 x 10-5. What is the pH at 25.0 °C of an aqueous solution that is 0.100 M in acetic acid? A) -6.61 B) +11.13 C) +2.87 D) -2.87 E) -11.13
Acetic Acid (CH3COOH) has a Ka value of 8 x 1-5. If I have a 0.15 M acetic acid solution, what are the following values? pH pOH [H3O+] [OH-] If I add 0..15 M sodium acetate to the solution what is the pH value here? Remember that pH = pKa + log [A-]/[HA].
Hop-OH но-р-он 1, 30. Acetic acid, OH, has a Ka-1.8 X 105 and a concentration of 0.4M. Using the dissociation equation below, complete the ICE chart. CH3CO,H CH3CHO2 + Initial Change Equilibrium 31. Calculate the equilibrium concentration value of the [H.] in problem 30.
12. Given that Ka = 1.8 x 10- for acetic acid. in order for an acetic acid solution to have a pH of 3.50, its molar concentration must be a. 5.7 x 10-3 M b. 5.6 x 10-3M c. 3.2 x 10-4M d. 2.3 x 10-M 13. If enough base is added to a solution to cause the pH to increase from 7.50 to 8.50, this means that А a. [OH-] increases by a factor of 10 b. [H'] increases...
