**2. CLAB 123**-------Please be prepared for the final exam. You will need a type F scan form and a calculator. Optional extra credit and UCM passes are also due.

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. This is a tough experiment so be prepared to work. 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 !0 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.

Experiment 10 instructions.

Unknown Letter (by names)

Raw data:

Room temp., Barometric pressure, Make a table - for each run give the mass of sample and the volume of water

Sample calcs.:

All the calculations that I did on the board.

Results:

Make a table for % sodium bicarbonate for each run and the average of the best runs.

Discussion:

Are your results precise and reasonable.

**3. CLAB 124**-------Please be prepared for the final exam. You will need a type F scan form and a calculator. Optional extra credit and UCM passes are also due.

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 10 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: A-voltages of single cell, parallel and series connected cells.

C- Masses of + copper electrode before and after and - copper electrode before and after. Table of current vs. time.

Sample Calculations: A- Theoretical value of voltage - single cell, series connected.

C- Calculate Faraday's constant as I did in class for + and - electrodes. Calculate % error for each electrode.

Results: A: Give measured and theoretical voltages for single cell, parallel and series connection.

B: Give 6 reactions. Put a check above the arrow for reaction that occurs and an X above the arrow for the reaction that does not occur. Finally, give the activity series.

Give the values you calculated for Faraday's constant and the % errors for both electrodes.

Discussion: Discuss your results.
