2. CLAB 124-------Please be prepared for experiment 9. You should read the introductory material and the procedure in your lab manual (or modification if applicable). Be sure to prepare an outline (summary) of the procedure in your notebook. Remember to bring your lab manual and notebook to class and wear proper lab attire. Please also bring a calculator (does not need to be scientific). Please study the link on the class web page for Common Laboratory Operations and Apparatus.

Your lab report for experiment 8 will be due. Please read Part II of the Information Sheet before starting the report. Remember that all calculations are to include units and are to be to the proper number of significant digits. Multiple pages must be stapled.

Raw Data- Mass of acid, volume of volumetric flask, volume of mixed acid dispensed, unknown designation, concentration of standard base.

Sample Calcs. - The two graphs and all the calculation I put on the board but for both equivalence points (two molar mass calcs and two % error calcs)..

Results - Volumes of NaOH used for each of the two equivalence points (from graphs), the two molar masses, the identity of the acid, the two % error.

Discussion - Discuss sources of errors.
