- 9 Test Tubes
- Test Tube Rack
- (2) Graduated Pipet, 10-mL
- Rubber Bulb
- Beaker, glass, 100-mL
- 0.01 M Silver Nitrate, 50-mL
- Unknown Solution, 50-mL
- Data Collection System
- Conductivity Sensor
- Wash Bottle with Deionized Water
- Gathered 9 Test Tubes, rack, and pipets and bulbs (Henceforth, assume them to be together, unless mentioned otherwise). Labeled test tubes with orange tape, as 1-9.
- Measured the prescribed amount of silver nitrate with one of the pipets, and deposited it into the associated test tube. Cleaned the pipettes, and placed them in the designated area for them to dry.
- Measured the prescribed amount of the unknown solution with the other pipet, and deposited it into the associated test tube, before covering each with Parafilm®, and shaking each thoroughly, to ensure that the solutions are completely mixed.
- Measured the conductivity of each solution (which had now had formed a precipitate), taking care to rinse the conductivity sensor with deionized water (including within the holes on the sides of the sensor), following each use.
- Collected the wash in the 100-mL beaker. Disposed of the contents of the beaker and test tubes in the appropriate container, cleaned them, and set them aside to dry. Returned all equipment to its point of origin.
