Buffers help
I only need help with part 2, however some information in part one might help! My unique pH is 2.00, [HA]=0.19M, [A-]=0.01M, [H3O+]=0.01M, and my ka is 5.263x10^-4 (at least I think this is right). Thanks!!

Please help. I got the graph for part 2. Don't know anything help. Please help with conclusion too Part and weak acids, 2: 1. Graph your data for the titration of acetic acid and sodium hydroxide. 2. The midpoint of the steepest increase in pH isthe equivalence use the equivalence point on your graph to estimate pKa and Ka for acetic acid. 3. Buffer capacity has a rather loose definition, yet it is an important property of buffers. A commonly...
Consider the titration of 50.00 mL of a 0.1000 M solution of a weak acid, HA, with a 0.0900 M solution of the strong base KOH as the titrant. Determine the pH at the equivalence point of this titration. The acid dissociation constant for the acid HA is Ka = 1.78 x 10-4. a. 9.01 b. 8.21 c. 5.79 d. 5.07
A thorough explanation would sure be appreciated!!!! Thank you!! Acid-Base Chemistry: Unknown Acid Analysis (in two experiments) Introduction In this experiment you will titrate a monoprotic weak acid with a strong ak acid with a strong base in the nd using a pH meter (Exp 2). An analysis of concentration and molar mass of the the titration data will allow you to determine the concentration and more unknown acid (Exp 1) and the ionization constant Ka (Exp 2). At the...
