The student should be able to:

1. Recognize and state the use of appropriate laboratory equipment
2. Define accuracy, precision and significant digits as they relate to laboratory measurements, and
where appropriate, calculate the percent error of experimental results relative to a standard
3. Given appropriate measuring devices and lab apparatus
        determine physical properties of substances using appropriate significant figures
4. Upon carrying out chemical reactions in the lab and given appropriate reference materials (i.e.,
      polyatomic ion formulas, periodic table, activity series and solubility rules) convert
      observable laboratory reactions to balanced equations
5. Given a set of data related to a specific experiment
      a. identify all measurable quantities
      b. recognize sources of error
      c. identify limitations of measuring devices in order to state the uncertainty in measurements.
      d. come to a valid conclusion based on the data
6. Given appropriate data, use stoichiometry to determine the formula of a compound.
7. Perform a titration and use the data to determine the number of moles of an unknown acid or base present,
      determine the solution concentration and operationally define titration, endpoint, equivalence point and indicator
8. Using chemical reactions in the laboratory, examine the factors that affect reaction rates, ncluding concentration,
      temperature, catalyst, surface area, and the nature of the reactants
9. Make models based on Lewis structures, and predict the shapes of the molecules
10. Prepare solutions of assigned molarity using dilution and other methods, and carry out associated calculations

30-Nov      Lab notebooks will be available one week after the final exam. Please note you need to use the student
    information system to access your final grade at the end of the term.
Class Policies:
1.     Withdrawal Policy:

Student-initiated: Any student who withdraws from the lecture must also withdraw from the lab or vice versa. The grade of "W" is given when the
      withdrawal is processed before the midpoint of the quarter. After the midpoint a grade of "WF" is assigned.

2.    Pre-lab session: A student who missed the pre-lab session will not be allowed to do the experiment, and a grade of Zero (0) for that experiment will
      be given. Pre-lab session/quiz starts promptly at Noon. In preparation for the lab you should review the streaming video for the lab. You will be
      given information on accessing the web site during the first class period.

3.    Safety Goggles: Safety goggles must be purchased by the students and must be worn at all times; these must be worn over prescription glasses.
      Contact lenses must not be worn in the lab.

4.    Science laboratories typically utilize material, which, if handled improperly, may have hazardous effects on your health. This is particularly true for
      those students who, because of existing health conditions, may be abnormally at risk. Examples of such but not limited to: wearing of contact lenses,
      pregnancy, nursing mothers, depression of immune system disease (chemotherapy, transplant patients, allergies, etc.). If you are in any of the above
      categories, or of aware of any condition that would make you especially susceptible to infection or toxicity from the substances commonly used in
      the lab for this course, you must advice your lab instructor so that your safety can be given appropriate consideration. These students mentioned
      above should contact their medical doctors for advice about continuing in the laboratory. Students who wish to withdraw from the laboratory after
      consultation with their doctor will receive a full refund for the laboratory provided they submit a letter from the physician within the first two weeks
      of the term. The physician’s letter must indicate that the student should not continue in the laboratory due to a health risk.

5.   Cheating: Any one caught cheating on a quiz, lab reports, and final exam will receive a zero (0) on that particular exercise and/or may be referred to
      the College Court. Read attached Academic Honesty Policy. Laboratory experimental data may be shared by lab partners; however, discussion and
      conclusion must be your own.

6.   Weekly Lab Reports are collected at the beginning of the pre-lab session. One point (1) penalty per day is assessed for late reports. Unexcused
      absence counts zero (0). NO lab reports are accepted one week after the due date.

7.    Lab notebook is checked and signed by the instructor before each experiment. Lab notebooks are taken up and graded at the end of the semester,
      at which point the instructor will check to make sure all the experiments are written according to the directions stated in the syllabus. However, lab
      notebooks may be collected any time without prior notice.

8.    Pre-lab quizzes: There is a weekly quiz given at the beginning of class. Questions may be taken from last week’s experiment and/or the present
      experiment. One lowest grade is eliminated.

Final Exam is cumulative. It may include multiple type questions, short answer questions, word problems with math, or a practical. Pointers for review will
       be provided.

Eating or drinking is not allowed in the laboratory.
                          The Lab Notebook:
Each student must obtain a standard hard-covered, permanently bound notebook (not loose leaf, not
    spiral bound), preferably with graphing papers. Entries in the lab notebook must be in ink. If any
    corrections in the entries are necessary, the student should mark one line through the incorrect
    entry. If the entire page is erroneous, the student should draw a diagonal (/ or \) line through the
    whole page. Write Omit at the top of the page. Each page in the lab notebook must be numbered.
    No erasures or whiteouts are allowed. No page should be ripped from the notebook. One (1) point
    is deducted for any unsigned exercise and ½ point for any violation of the lab notebook policy.
                            The Lab Notebook   (format)

Title page (First page):

      Student’s name, course title,
    section number, semester, and year
                                                      Your name

Table of Contents (second page):

    This page should include
    experiment numbers as listed in
    the syllabus (same numbers as in
    the lab manual), titles of the
    experiment, and page numbers in
    the student's laboratory notebook
    (not page numbers in the lab
    manual) where the experiments are
    located. See sample below.
                       The Lab Notebook:

For each Experiment:

1.           Date and page number: The date on which the experiment is done
            and the page number are written on the top right of the page. The
            first page of each experiment should b e a right-hand page in the
            lab notebook.

2.          Title: The title of the experiment should be at the top (center) of
            this page.

3.          Introduction and background information for that particular
            experiment: Each experiment is based on concepts that reinforce
            the lecture. A paragraph or two stating the concept(s) and
            background information of the experiment must be written after
            the title.

4.          Goals: Write in your own words...

                                 The Lab Notebook:

6-       Conclusion and Discussion: This is added into your notebook after
         completing the experiment. For each experiment write legibly, (typed and
         pasted if possible), your conclusion and short discussion of the results. What
         did you learn from this experiment?

7-       LAB REPORT : The following week, turn in page(s) posted with the schedule
         of the experiments. This constitutes your weekly report grade. Photocopies
         will not be accepted.

At the end of the semester all experiments must be turned in. These are not returned
    back to the students.
