In figure 14.5, each curve the concentration or acid and base are the same, e.g., the curve labeled 1M is for the titration of 5 drops of 1M weak acid with 1M NaOH. Why are the titration curves for the different reagent concentrations so similar in the buffer region? Are these solutions all buffers? please explain me with details thanks!

Carry out a serial titration of one drop of the weak base 0.05 M NH, (aka NH,OH) with 0.01 M HCI. Stir. Measure the pH values of the solutions. Plot the titration curve on the same graph with your strong acid/strong base and weak acid/strong base titration curves. Compare with the computer-simulated curve (Figure 14.7). NOTE: Data from the computer calculation give an equivalence point pH of 5.70 at 5.0 drops of added 0.01 M HCI. Observations: Lane 1-purple (pH...
Can you please answer the part i underlined? Thanks!!

2. Write reaction equations to explain how your acetic acid-acetate buffer reacts with an acid and reacts with a base. 3. Identify the Pka of acetic acid from your data. Advanced Chemistry with Vernier Buffers 4. Buffer capacity is usually defined as the pKa Il pH unit- that is, the pH range over which the ratios of protonated to unprotonated form of the buffer go from 10:1 to 1:10. Use your data to determine the buffer capacity of your buffer...
Question: In the figure below, titration curves for strong acid with strong base and weak acid with strong base are shown. Compare the shapes of these curves early in the titration for three different cases: titration of a strong acid, titration of a weak acid with a lower pKa, and titration of a weak acid with a higher pKa. Discuss with the class why the titration curve for weak acids increase more rapidly early in the titration than do stronger...
Given that the pKa for the half equivalence point is = 5.5, and the pKa of Acetic acid is 4.76, what is the percent error? Is 4.76 the accepted value? and 5.5 the experimental? and so... |4.76-5.5| = -0.74 --------- ----- = 0.15546 ×100% = 15.55% |4.76| |4.76| Please verify I am correct.
