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...

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!
