Laboratory Report Template Instructions
The first 6 pages of this document contain hints & instructions for using the
template and formatting the report.
Delete these pages and any unused procedure pages from the copy being
turned in for grading.
Add a New Page – place cursor on blank line below last table on page before
you want to add a new page. Click on “Insert” in Menu Bar. Select
“Break.” Select “Page Break.”
Enter Information into “Header” table at top of page
Word 2003 - Click on “View” in Menu Bar; select “Header & Footer.”
Enter required information. Text will flow to to the Header at the top of
each page. .
When finished, click on “View” again and select “Print Layout” to return to
normal data entry.
Word 2007 – Right click in Header box. “Edit Header” box appears. Left
click in “Edit Header” box. Enter required information. Text will flow to
the Header at the top of each page.
When finished, click on “view” in Menu bar. Click on “Print Layout” to
return to normal data entry.
Continue data entry in table over onto a new page
With cursor inside a table, click on “Table” in Menu Bar.
Select “Table Properties.” Select “Row.”
Under “Options,” click on box to “Allow Row to Break Across Page.”

 Experimental Reactions Page (Stoichiometric Equation, Molar Ratio,
Reaction Mechanism)
This page, which is a Procedure (usually Procedure 3 or 4) is to be included
in any report dealing with a Synthesis Experiment.
It is to be placed on the page following the final computation of the Mole
values and just before the “Limiting Reagent” procedure.
To move the table to a different page, move the cursor over the table until a
box appears in the upper left (or right) hand corner. Right click on this box
and select “Cut.” Go to the page to hold the table and paste it into place.
 Theoretical Yield (Mole Table) Summary Table
This table is to be placed on the page following the calculation of
“Theoretical Yield.” Note: Delete the explanatory text on the page as well as
the table not being used.
 Adjusting size of cells in tables
Note: The entire template is a series of tables.
If a cell appears to have excess unused space, especially at the top or the
bottom of the table, do the following:
 Place cursor in lowest point in cell and backspace through all
unnecessary line breaks to the point where your text ends.
 Place the cursor on the bottom line of the cell (a double line will
appear).
 Move the cursor up until the desired cell size is attained.

 Click on a location on the “Ruler” line to insert a “Tab.”
 To move text to a Tab position Press & Hold the “Ctrl” key while
pressing the “Tab” key.
 Delete a Table from the report
 Move the cursor over the table until a box with an “X” in appears in
either the upper left corner or upper right corner of the table.
 Right click on the box.
 Select “Cut” to remove the table.

Lab Report Structure
The Limiting Reagent
Whenever an experiment involves a "Synthesis" of a compound, a series of
calculations must be performed before you begin the experiment (in terms
of the report structure)
These calculations ultimately result in the determination of the "Theoretical
Yield." The steps, i.e., procedures, required to get to the theoretical yield are
as follows:
• Determine the Mass of the first reagent
• Determine the Mass of the second reagent
Note: If the determination of the two masses both involve the same
technique, e.g., weighing on a balance, then a single procedure can be used,
otherwise two procedures.
• Compute the moles of both reagents.
• On the reactions page, set up the Stoichiometric Balanced equation and
determine the Molar ratios between the reactants & products.
• From the "Actual Moles" of reagents used and the Theoretical
Molar Ratio, determine the Limiting Reagent (show the calculations).
• Using the Limiting Reagent and the Theoretical Molar Ratio
determine the Theoretical Yield in grams.
Mixing the Reagents and Initiating the Reaction
Once the Theoretical Yield has been determined for a “Synthesis”
experiment, the report can now focus on the actual experimental
procedures.
The initial procedure usually involves obtaining and mixing the reagents.
Following the main reaction, it is usually necessary to perform one or more
procedures to separate the product from the reaction mixture, e.g., Vacuum
Filtration, Liquid / Liquid Extraction, etc.
After separation, additional procedures are used to clean up or purify the
product using Liquid/Liquid Extraction, Recrystallization, etc.

Identification of an Unknown Compound
For an experiment involving the identity of an Unknown compound, the
Theoretical Yield computations are not involved.
The unknown sample should be considered impure and therefore, the first
procedures in this type of experiment usually involve purification of the
sample, using such techniques as Simple Distillation for liquids or maybe
Recrystallization for a solid.
After purification, the sample is usually subject to a series of tests to provide
data for evaluating its identity and structure, such as Boiling Point,
Solubility & Density relative to water, Refractive Index, Melting Point, IR,
NMR, etc.
Procedure Descriptions
In General, a procedure should be started on a “New Page.” Two or more
procedures can be placed on a single page if they can be accommodated in
their entirety, without crowding.
The left side of the page is used to describe the procedure, using complete
sentences in a “Bullet” format.
If the procedure involves a computation, describe and set up the equation
being sure to define the variables used.
Each procedure has a "Results" section on the "right side" of the page. This
is where you report your observations, make the actual calculations, or
otherwise state the results of the procedure.
Calculations for ALL results must be shown.
Note: The results are not analyzed in the “Results” section, just reported.

Results Summary
Once all of the procedures are completed and you have accumulated the
experimental results, you then set up a new procedure to summarize the
results – ALL RESULTS - using a "Paragraph" format.
Analysis & Conclusions
After you have summarized the results, the results are then analyzed in the
“Analysis & Conclusions” section with data supported arguments to
support any conclusions you have about the results.
NOTE:
Do not modify any of the table formats. If a cell is not
applicable to your report, leave the cell blank.
