Do you need a quicker lab for your students to make a buffer and titrate it? I've written one up that you can do in under 45 minutes! This lab allows students to make a buffer with 50-mL of 0.1M acetic acid and 0.34 grams of sodium acetate. This buffer will hold the pH at 4.7. Then, students titrate a portion of their buffer with 1M NaOH and take pH measurements after every 1-mL addition. They draw a titration curve from their data. Then, students repeat this same titration using 1M HCl instead of 1M NaOH. Students calculate the expected equivalence point pH and then confirm in on their graphs!
This product includes teacher instructions, a student lab sheet (with procedures) and an answer key. These items are in WORD format, so they're fully editable.
*You do need the following materials:
0.1M acetic acid
sodium acetate solid
pH meters or sensors
software or a FREE Vernier chromebook app if pH sensors are used
