- State chemical names and formulas that are commonly used in wastewater analyses.
- Identify and describe equipment in a wastewater laboratory.
- Demonstrate techniques used during standardization and titration procedures .
- Demonstrate proper use of a spectrophotometer and graph the calibration curve of a sample.
- Identify and select best indicator to use for water sample testing.
- Organize test data, by using bench sheets, and keep accurate records.
