This course emphasizes the safe analysis of natural samples where interfering elements or substances must be removed before the final analysis, with particular emphasis on safety awareness and application. The student will gain experience in weighing, moisture and ashing; use of the muffle furnace; gravimetric separations and analysis.This course emphasizes the safe analysis of natural samples where interfering elements or substances must be removed before the final analysis, with particular emphasis on safety awareness and application. The student will gain experience in weighing, moisture and ashing; use of the muffle furnace; gravimetric separations and analysis; volumetric separations and analysis, including acid-base, redox and complexometric determinations; ion exchange separation and analysis; spectrophotometric analysis.

The attendance policy as outlined in the current BCIT Calendar will be enforced. Attendance will be taken at the beginning of each session. Students not present at that time will be recorded as absent.

Advancement: Students who fail three or more courses in a term cannot advance to the next term and may be asked to discontinue from the program.

Required: Laboratory coat
Required: Safety glasses (Note: Contact lenses are prohibited in the laboratory)

Upon successful completion, the student will be able to:

1. Recognize basic volumetric glassware and lab equipment and know how to select the appropriate glassware for the tasks at hand.
2. Describe glassware classifications, specifications and tolerances of volumetric flask, burettes, pipettes and bottle-top dispenser.
3. Describe the terms 'To Contain' and 'To Deliver'.
4. Describe the factors affecting the accuracy of volumetric glassware.
5. Understand statistical analysis and the terms mean, standard deviation and relative standard deviation to the analysis of data.
6. Explain the concept of a primary standard and its properties.
7. Explain the use of filtration equipment, the different types of filter media and filtration methods.
8. Set up different types of apparatus with the correct relative positioning of the equipment pieces. In particular, when several pieces of apparatus are involved, set up will involve the proper relative positioning of each piece of equipment.
9. Label samples using the proper technique.
10. Clean-up small spills using proper techniques and safety equipment.
11. Demonstrate the techniques to obtain accurate measurements using volumetric glassware. This includes proper filling, setting, delivery time and reading techniques of glassware.
12. Demonstrate the correct manner of using a variety of pipette bulbs (single bulb).
13. Use proper transfer techniques with measuring pipettes and volumetric pipettes
14. Choose a primary standards and preparing primary standard solutions from solid reagents and by dilution.
15. Assemble and prepare a bottle-top dispenser for use.
16. Calibrate an analytical balance
17. Demonstrate weighing by taring, weighing by difference and list the errors associated with weighing.
18. Perform a titration with a burette.
19. Complete the procedure for gravity and suction filtration.
20. Practice solvent selection in extraction.
21. Demonstrate using a separatory funnel, and the operation of a rotary evaporator.
22. Prepare a set of standard solutions by dilution.
23. Prepare a properly titled and labelled calibration graph by graphing by hand and know how to use it to determine the concentration of unknown samples.
24. Prepare a properly titled and labelled calibration graph by using a spreadsheet tool, perform a trend line analysis and know how to use it to determine the concentration of unknown samples.
25. Perform statistical calculations with a basic scientific calculator in statistical mode to determine the mean, standard deviation and relative standard deviation.
