STUDY GUIDE    Summer 2009
Total Points: 234 (Final Exam) + 44(Quiz) = ~284

1) 44  points Simple, Short Answer Problems on: Density,  Interpolation,  Dilution, Acid Base Titration,  pH,  Gas Laws, Calorimetry, Beer's Law, Limiting Reagent in Solvay Process.
NOTE: The GRADE on this page will count both as your QUIZ GRADE as well as being part of the FINAL EXAM.  These 44 points really count as 88 points in your overall total points. 

2) Chemical glassware; How to read a buret, meter and thermometer. Know: Balances; Your DATA SHEET-a legal record; Use of acid base indicators-phenolphthalein and litmus. What are the first things you enter on your DATA sheet.
Know approximate pH of the "common solutions" you studied in the pH experiment. What produces a sour taste.

3) Calculate: the density of a liquid and/or the density of an irregular solid given experimental data similar to those you obtained in Exp. 2  using a one hole stopper pycnometer.
Calculate: the % water in a hydrate and/or the formula of a hydrate.

4) Properties of gasses studied in Exp. 13,  NonMetals; The environmental aspects of these gasses; their formulae. Understand Acid Rain, Global Warming, the Greenhouse Effect.
Chromatography how to do it and what it does. Calculate: Rf 
Simple conversions i.e., mg, ng, g.; atmosphere, mm Hg, torr;  L, mL; etc

5) Calculate: w/v% of acetic acid in vinegar and/or M of NaOH using KHP as a Standard. Solve Problems on: Titration of vinegar;
The Molecular Weight of a Liquid by the Method of Dumas.

6) CALORIMETRY; Specific Heat and Atomic Weight (Rule of DuLong and Petit) of a metal  calculations.
You will be given observations on reactions of X, Y, Z,  with A, B and C. You are to write directions (10 pts) for identifying an UNKNOWN containing X, Y or Z. using reagents A, B and C. This is similar to what you did in the Periodic Table Experiment  however X, Y and Z  and A, B and C will be something you haven't seen before. 

7) Calculate Molar Volume of Oxygen from volume and mass of gas collected from decomposition of KClO₃.
Calculate the % KClO₃ in a sample from mass of Oxygen collected.
Calculate % error in calculations given % errors in each measurement.

8) Calculate: the Eq.W. of a metal using the amount of H₂ it generates and/or the amount of H⁺ used in dissolving the metal. Be able to calculate % errors in the Equivalent Weight given small errors in the experimental values.
Write and balance simple equations for reactions you carried out this semester.

9) Copper Analysis: Calculate: the concentration of the Standard. Solution, convert %T's to A and calculate the W/V% of copper in an UNKNOWN given a set of data.
Effect of errors (fingerprints on cuvet, parallax error) on results in this experiment.
Calculate % error in calculated concentrations given errors in readings.
