GENERAL CHEMISTRY LABORATORY, Spring 2017
Thursday, May 4, 2017 11:45 AM – 2:45 PM
Smith 220,, Boyden 100 and Conklin 100... Assigned Rooms and Seats
Please check your Grade Record to make sure it is correct.
A- Rooms and Seats will
be assigned; see above.
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 240+ 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 240-250 points.
Page 1 about 35-40 points, will also count as a quiz.
TOTAL POINTS 240-250 + 35-40 = 275-290
STUDY GUIDE (Final guide will be posted later)
1) The first page will have about 10 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. Topics will cover density, metric units, dilution and concentration, equilibria involving pH and Ksp.
The remaining 8 pages involve calculations and conclusions similar to those you made on the PreLabs and experiments.
2) True –False statements. Taken from the true-false quiz you passed to start most of the experiments.
3) Titration ( this semester you used titrations to determine calcium in hard water, the molecular weight of an unknown acid, and the concentration of Hydrogen Peroxide)
4) Colligative Properties... involves mainly Molecular Weight by freezing point depression.
5) Know the calculations and logic of the pH and Buffers experiment. This includes buffers, titration curves, Ka, hydrolysis of salts, indicators etc.
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, the Principle of LeChatelier and Ksp
8) With regard to the Kinetics 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) Spectroscopy... Use of spectrometers; use of Beers' Law in analysis.
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.
