2. CLAB 123------- Please be prepared for experiment 10. 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 reports for experiment 9 will be due.

You may use the table in your lab manual for the presentation of raw data and results. Be certain to show your sample calculations to the proper number on sig. figs. All of the calculations that I did in class should be done for one run of each of the two preparations. You do not need to calculate the moles of HCl because HCl is excess.

Please read 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.
