How to fill out Chem 111 Lab: Acid-Base Titration (B)—Equivalent Mass

1. Gather all necessary materials, including a burette, pipette, acid, base, and indicator.
2. Rinse and fill the burette with the titrant solution (usually a strong acid or base).
3. Use the pipette to measure a specific volume of the analyte solution (the solution whose concentration you want to determine) into a clean Erlenmeyer flask.
4. Add a few drops of the indicator to the analyte solution in the flask.
5. Place the flask under the burette and slowly release the titrant from the burette, swirling the flask to mix.
6. Continue adding the titrant until you observe a color change indicating that the endpoint has been reached.
7. Record the volume of titrant used from the burette.
8. Calculate the equivalent mass of the acid or base using the volume and concentration of the titrant.
