Strong Acid/Strong Base Titration

AP Chemistry Titration Curve Handout From John Hnatow @ Goucher College (Baltimore, MD) on the AP Chem Teacher Community Name ______

You may use the titration simulation (http://chem- ilp.net/labTechniques/AcidBaseIdicatorSimulation.htm) provided on the titration webpage. First Goal of this handout 1) To identify the type of titration simply by looking at the titration curve a. is it a strong acid being titrated with a strong base? b. is it a strong base being titrated with a strong acid? c. is it a weak acid being titrated with a strong base? d. is it a weak base being titrated with a strong acid? e. is it a weak base being titrated with a weak acid f. If an acid is being titrated, is it a mono-, di-, or tri-protic acid

2) You need to fill in the blanks at the top of each titration curve in the following manner: a. fill in the first blank with the type of solution being titrated (what is in the beaker/flask being analyzed) b. fill in the second blank with the titrant (the solution being delivered from the buret Example: if a weak acid was in the beaker and it was being titrated with a strong base from the buret, you would write: Weak acid/Strong Base

3) Give reasons for your selections based on what you see in the titration.

Second Goal of this handout Second Day 1) Analyze each curve to find the equivalence point(s) 2) Using the equivalence point(s); a. Determine the Ka(’s) or Kb(‘s), when applicable b. Use your text to identify an effective indicator that could be used to show the endpoint in a titration c. Determine the concentration of the sample being titrated, assuming the titrant is 0.100 M and that 10.0 mL of sample was titrated each time.
