CHEM 114   GENERAL CHEMISTRY LABORATORY,  Summer 2009
FINAL EXAMINATION ...Summer 2009
Monday, August 10, 2009     8:30 - 11:30 AM 
 Conklin 100...  Assigned Seats
Please check your Grade Record to make sure it is correct.

A- Seats will be assigned.
B- You may use ONE, hand-written (not xeroxed) 4" X 6" card of notes (BOTH SIDES).
C- Absolutely NO CELL PHONES. Not even for use as clocks or calculators!!!!
D- You will need a Non Programmable calculator (with logs)
E- You will need a straight edge and writing tools (pencil or pen).
F- Since the Letter Grade Range in this course are about 150 points and this will be a  220+   point test, your grade may be lowered as much as one letter by a very poor performance.

The test will have 9 pages of questions and a total of 220-250 points.
Pages 1 and 2, about 40-50 points, will also count as a quiz.

1, 2) The first two pages will have thirteen  3-4 point   "simple" calculation problems and short answer questions. This will also count as your quiz grade so each question actually will be worth 6-8 points;  3-4 points for the final and 3-4 points for your quiz.

The remaining 7 pages involve calculations and conclusions similar to those you made  on the PreLabs and experiments. 

3) Be able to read burets, meters and thermometers. Know the effect of experimental errors on the results. Calculations of % error, maximum error.

4) Be able to make an EDTA Titration calculation and a MW by Freezing Point Depression calculation.  Interpret a cooling curve. What is hard water?

5) Know the calculations and logic of the pH and Buffers experiment. This includes buffers, titration curves, Ka, hydrolysis of salts, indicators etc.
You will be given data from CuAg.  Be able to calculate Molarity of a copper solution and moles of silver precipitated.

6) You will get a 9 test tube mystery including two acids and two bases to solve. These will be similar to your 10 TT Mystery but not identical. You will be asked to write equations for the more obvious reactions (amphoteric, acid-base complex formation, etc)

7) Equilibrium and the Principle of LeChatelier.  Understand  a standard plot.

8) With regard to the Kinetics (Grocery Store Clock) experiment. Know the theory. Be able to plot variable temperature data and read the plot. Be able to handle the rate equation.  Be able to calculate time for reaction to take place.  Calculate a rate constant at a new temperature.

9) Be able to calculate the Ksp of Lead Iodide given a set of data. Why is constant ionic strength important in this experiment?  What is the function of Potassium Nitrate? of Potassium Nitrite?  Spectroscopy and the use of Beers Law.
Be able to calculate the molarity of a Hydrogen Peroxide sample .

ALMOST ALL THE QUESTIONS ARE BASED ON THE EXPERIMENTS YOU CARRIED OUT THIS SEMESTER.
Review these experiments in your manual, PRE-LABs, returned Experiments and the web-sites using this study guide.
