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.Homework Answers
In this titration we use first 1 M weak acid. Due to this reason, the Y axis (ph level) is not going to much low and coming around 3-5 and when we use base(NaOH) of 1 M, it makes salt ( already we know that acid and base combined to form salt). When we use 5 drops of 1M NaOH, it makes buffer solution ( weak acid and cojugate base). There is a equilibrium takes place between weak acid HA and cojugate base A-. Due to this reason titration curves are similar for different concentration. Yes all are buffer beause here we are taking weak acid and conjugate base.

Consider Figure 14.5. For each curve the concentration of acid and base are the same, e.g., the curve labeled 1 M is for the titration of 5 drops of 1 M weak acid with 1 M NaOH. Why are the titration curves for the different reagent concentrations so similar in the buffer region? Are these solutions all buffers?

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...
