• Ring Stand
• Clamp
• Beaker (2), 100-mL
• Beaker, 50-mL
• Hot Plate/Magnetic Plate
• Automatic Titrator
• Jar with custom-made hockey puck-derived lid, 180-mL
• Hydrochloric Acid, unknown concentration (approximately 6M), 70 mL
• 0.0200 M Sulfuric Acid, 50-mL

Method:

• Gathered all equipment and materials. Inspected all equipment for damage or contamination.
• Set up Data Collection System, assembled GLX, and conductivity sensor.
• Set up Automatic Titrator, ring stand, Hot Plate/Magnetic Plate, and attached the Jar with custom-made hockey puck-derived lid.
• Placed the conductivity sensor so that it would be suspended in the jar, and attached the magnetic stirrer to the end of the sensor.
• Flushed Automatic Titrator with deionized water, to minimize contamination, before filling with 50 mL of 0.0200 M Sulfuric Acid.
• Acquired 50 mL of Barium Hydroxide, and poured into Jar.
• Added deionized water until the solution covered the tip of the conductivity sensor.
• Turned on Magnetic Stirrer, checked all connections to ensure that they were secure, checked the Automatic Titrator to ensure that no bubbles were present within it, then began titrating.
• Recorded the Data via the GLX, generating the graphs used.
• Disposed of solutions in designated containers. Cleaned all glassware, set them to dry in their designated areas, and returned all equipment to its point of origin.
