Question 9: Consider a titration in which 0.03 M NaOH is added to 1 drop of 0.12 M HCl. Sketch the pH curve. sketch is a rough picture of the general shape of the curve with the requested points and axes correctly labeled. If it is easier, sketch on paper and insert a photo of your sketch. On your curve, show: (a) The volume of 0.03 M NaOH needed to reach the equivalence point. A
(b) The pH at the equivalence point.
(c) The pH at the beginning of the titration before any 0.03 M NaOH has been added to the 0.12 M HCl.
(d) The pH when you are well past the equivalence point.

Question 10: Considering your data for methyl orange, bromocresol green, bromothymol blue, and phenolphthalein (Figure 14.3), which indicator would be the most suitable for a titration between 0.001 M HNO 3 with 0.001 M KOH solution? Explain your selection.

Section E. Part 2. Titration of a Weak Acid with a Strong Base Watch the video associated with this section and read along in your Chemtrek. There are several observations you should be able to make in this section and it may be helpful to record your observations in a table. Create a titration curve using the data from the video and attach the titration curve at the end of this section.
Remember to attach your titration curve to the end of this section. This can either be done electronically and inserted into the space below or created by hand and included as the next page of your report. Figure 3: Titration Curve between Weak Acid and Strong Base Section E. Part 3. The Measurement of the K a of a Weak Acid from the Titration Curve This is a conceptual section. Read through the material in your lab manual carefully and summarize this section below. Look at Figure 14.4 included in the lab manual file and determine the K a for acetic acid. Record this value below.
