Each of you will receive a notebook for Qualitative Analysis. All work must
be done in the qual notebook in ink.
Only procedures and unknown identifications in
the notebook will be graded.
If you forget your notebook, you cannot move on to the next unknown.
Directions for setting up the notebook.
On the outside cover, on the label write your Qual ID number (given to you
by the teacher). On the inside cover write your name.
Label the upper right hand corner of the 1st 10 pages with your Qual ID
Number and the page Number.
Starting at the back of the notebook, copy the solubility rules to
the first page inside the back cover. (Refer to these if you get confused.)
Copy the definitions from the hand out to the next page or pages
behind the solubility rules (depending on your handwriting). Refer to these definitions so that you can
follow instructions properly.
Bring the completed notebook to Mr. K to be initialized. You are now ready
Start each Unknown on a fresh page. For each step keep in mind you
|What you did (Procedure Number and reagent)|
|What you saw (Color change, precipitate, dissolving, etc.)|
