CHEM 1525: Chemistry Laboratory II

Note: This course is only available for registration to students residing in Canada.

This course is the second laboratory for a fundamental first year chemistry course, designed for students who have a Chemistry 11 background. This course provides the equivalent of a first-year university chemistry course when taken with its accompanying theory course, CHEM 1523. The topics include a review of laboratory safety and equipment, anion and cation identification, properties of gases, thermochemistry and caloric content of food, equilibrium and Le Chatelier's principle, reaction order and rate of reaction, acid-base titrations, buffers, acid-ionization constant (Ka) determination, oxidation-reduction reactions, and electrochemical cells. Students are expected to become familiar with these topics, and demonstrate their proficiency in various laboratory techniques.

Learning outcomes

By the end of this course, students should be able to:

  • Demonstrate and have an appreciation of basic laboratory safety concepts
  • Demonstrate basic handling/clean-up of chemicals
  • Demonstrate organized recording of experimental and observational data
  • Display experimental results in data tables, construct and compare titration curves, and interpolate values
  • Use paper chromatography to separate and identify mixtures
  • Perform acid-base titrations using pH indicators and describe the neutralization reactions
  • Perform dilution calculations and prepare standard solutions of known concentrations
  • Determine the concentration of an unknown sample and compare to listed values
  • Describe and prepare buffer solutions
  • Perform oxidation-reduction reactions and relate to activity series
  • Set up and use an electrochemical cell and compare experimental and theoretical cell potentials
  • Demonstrate basic chemistry lab techniques such as reading scientific scales, performing accurate measurements, titrating, using volumetric glassware , and using a multimeter

Required text and materials

1. CHEM 1525 Labkit from Labpaq

The lab kit provides equipment, chemicals, and anything else that students will need to do the experiments and cannot provide for themselves. Some common materials, like vinegar and other household items students may need to supply.

Additional requirements

Computer with Internet Connection: Digital Camera: Students will need to have access to a digital camera during the experiments to take photos and videos of their progress.

Web cam: Students will need a computer web cam in order to demonstrate their work in the practical component of the final exam. For more information, please read the "Assessments" section in this Course Guide Overview.

Microphone headset: To communicate with the Open Learning Faculty Member during the practical component of the final exam, students will need computer speakers or headphones, and a microphone. (A computer headset should be sufficient.)

Skype Account: Students will need a Skype account in order to demonstrate their work in the practical component of the final exam. Skype accounts are free, and students can register for an account at If students are unable to use Skype, please contact the Open Learning Faculty Member to make an alternative arrangement.

Calculator: This course requires a non-programmable, single-numeric line calculator, such as the Casio fx-260. This course does not permit textual input calculators, electronic devices, paper dictionaries, or translation devices to be used on the final exams. We reserve the right to inspect any student calculator during the final exams.

Optional materials

A first-year Chemistry textbook would be helpful.


Please be aware that should your course have a final exam, you are responsible for the fee to the online proctoring service, ProctorU, or to the in-person approved Testing Centre. Please contact with any questions about this.

To successfully complete this course, students must achieve a passing grade of 50% or higher on the overall course and 50% or higher on the mandatory Final Laboratory Exams.

Assignment 1: Safety Quiz 5%
Assignment 2: Online Journal (Experiments 1-5) 10%
Assignment 3: Reports (Experiments 1-5) 20%
