This preview shows page 5 - 6 out of 6 pages.

Chemical name: acetic acid Common name: vinegar Formula:C 2 H 4 O 2 Molecular formula:60.05 g/mol Boiling Point:118.1°C 244.6°F Melting Point: 16.6°C 61.9°F Structure: Hazards: keep away from heat, don’t ingest, avoid contact with skin. Procedure: 1) To minimize error due to bad technique, there will be two trials for the titration and the results are then going to be averaged. Get a 10 mL graduated cylinder, 150mL beaker, 250 mL beaker, and a 125mL Erlenmeyer Flask. 2) Obtain the 250 mL beaker and the 150mL beaker to the supply cart at the front of the laboratory. In the 150mL beaker place just over 20mL of vinegar. For the 250mL beaker, pour just over 70mL of sodium hydroxide and return back to your lab station. 3) Set up a ring stand, a burette clamp, and a burette.

4) Wash and then fill the burette with Sodium Hydroxide, and then remove the air bubble from the tip of the burette. Zero the burette and record the volume and write it down on the report sheet. Should be 0.00mL because no base has been added. 5) Rinse the 10mL graduated cylinder with vinegar. Measure out the 10 ml of vinegar and place it in the Erlenmeyer flask, and then proceed to rinse the graduated cylinder with deionized water and add it to the flask.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
