Below is a list of resources helpful in completing the lab assignments for CHEM 235. If you need help in using these resources, please contact the chemistry librarian.

Inversion of Sucrose with Acid as a Catalyst
Because this is likely to be an older, "classic" article published in the early 1900's, you may have trouble finding something good in SciFinder Scholar (older articles are not completely indexed).
Instead, try searching the American Chemical Society journal package online. Concordia subscribes to the archives of these journals as well as the newest journals. Their search function is quite good. Here's how to search:
- Go to the ACS e-journal package search page. You can use it from home using your library PIN.
- In the "Anywhere in Article" search box, type acid.
- In the "Title" search box, enter inversion of sucrose.
- Hit the search button! You should get a number of hits that are useful. You can link directly to the PDF of the article.
Another source that is quite useful is the book Experimental Physical Chemistry. You will be able to find references to measurements of the rate of inversion of sucrose in this text.
Decomposition of Hydrogen Peroxide Catalysed by Iodide Ion
As in the first experiment, the kinds of papers you're looking for are classic works, but you may also find some newer articles that are useful too.
- Try searching the American Chemical Society journal package online. Concordia subscribes to the archives of these journals as well as the newest journals. Their search function is quite good:
- Go to the ACS e-journal package search page. You can use it from home using your library PIN.
- In the "Anywhere in Article" search box, type iodide.
- In the "Title" search box, enter decomposition hydrogen peroxide.
- Hit the search button! You should get a number of hits that are useful. You can link directly to the PDF of the article.
- The International Critical Tables is an old book that now has an online equivalent - it's a bit slow and difficult to use, but it can be an excellent source. Click here to search the tables.
- Scroll down the table of contents. In Volume VII, there is a chapter on "Kinetics of Chemical Processes". Open the chapter by clicking on the (+) sign next to the chapter name. Within this chapter, you will see a section called "Chemical kinetics". Click on the (+) sign for this section.
- Within the Chemical Kinetics section, the "Experimental data" should have what you are looking for. Click the Text link next to "Experimental data". A pdf document will open. Do a "find word" search for iodide. This should bring you to the section on the decomposition of hydrogen peroxide catalyzed by iodide, which contains k values and references (contact the Chemistry Librarian if you have trouble understanding the references).
Bromination of Acetone (in H2SO4)
Try searching the following:
- SciFinder Scholar is a good database to search - Not accessible from home. Search this database from Vanier and Webster Libraries' workstations (Start menu) or from computers within the Concordia IP range. Do a "research topic" search on kinetics of the bromination of acetone in acid. You should get a number of good hits. Click on the paper icon to get the full text of the article.
- American Chemical Society journal package online.
- In the "Anywhere in Article" search box, type (bromination or halogenation) and acid.
- In the "Title" search box, enter acetone.
- Hit the search button! You should get a number of hits that are useful. You can link directly to the PDF of the article.
- Journal of Chemical Education. Enter the search term (in the title) halogenation of acetone. You should get at least one result.
Methanolysis of Diethyl Acetal (to dimethyl acetal)
Try searching the following:
- The American Chemical Society journal package online:
- In the "Anywhere in Article" search box, type methanolysis.
- In the "Title" search box, enter kinetics and acetal.
- Hit the search button! You should get a number of hits that are useful. You can link directly to the PDF of the article.
- SciFinder Scholar also has some good hits - Not accessible from home. Search this database from Vanier and Webster Libraries' workstations (Start menu) or from computers within the Concordia IP range. Do a "research topic" search for kinetics of the methanolysis of diethyl acetal.
Iodine Clock Reaction
This is a classic chemistry experiment so the, so try searching the following:
- Journal of Chemical Education. Enter the search term (in the title) iodine clock reaction. You should get a couple of good results.
- SciFinder Scholar - Not accessible from home. Search this database from Vanier and Webster Libraries' workstations (Start menu) or from computers within the Concordia IP range. Try a "research topic" search for kinetics of the iodine clock reaction. You should get some good hits.
