1. Data Analysis: Make a titration curve from data you collected. Determine the concentration and the Ka of the unknown acid sample. Show any calculations you use to obtain the answers. 2. Experimental results: Summarize your results in a clear and concise way. Include the following: a. The unknown set number or letter b. The volume of acid used in each titration c. All titration curves d. From each titration, the Ka value and how it has been determined. The average value of Ka. 3. Discussion Questions: a. How do you estimate the percent error of your deetrminations without knowing the identity of your unknown? b. Which method is more reliable? Why? c. Error analysis: List the most possible sources of error. Do not give a long list of all possible sources. Give only one or two most obvious problems.
