Safety Considerations

Acids and bases can be harmful to both your skin and eyes.

Wear eye protection and wash hands regularly to avoid having harmful materials

come into contact with your eyes.

If you spill acids or bases on your skin, immediately wash thoroughly with soap

and water.

Disposal of Waste

All waste and excess reagents should be disposed of in the labeled waste

container in the room.

Laboratory Activities

This week’s lab is designed to help you learn, demonstrate, and improve on your

titration techniques.

Part One

Show proper cleaning and filling of buret with water and read the buret

appropriately: Each person should demonstrate how to do this to their laboratory

partner. Your laboratory partner needs to sign-off in your notebook that it is done

properly. When checking your lab partner look for the following items:

•Is about 15 mL of liquid used to clean?

•Are inside walls coated with liquid and run out of tip?

•Is rinsing repeated at least twice?

•Is buret filled with water and meniscus is inside of volume markings?

•Is the tip of buret filled with water and free of air bubbles?

•Is the volume of buret recorded appropriately?

•After both lab partners have cleaned the buret with water, rinse and fill

your buret with NaOH for the remaining parts of the experiment.
