Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use a pH sensor to demonstrate the properties of buffer solutions and buffer capacity.
Students learn the properties of buffer solutions and buffer capacity.
Students gain experience conducting the following procedures:
Beaker, 25-mL - 2
Graduated cylinder, 250-mL
Magnetic stirrer and stirring bar
2.000 M Sodium hydroxide (NaOH) - 250 mL
0.1 M Acetic acid (HOAc) - 250 mL
0.3 M Acetic acid (HOAc) - 250 mL
0.5 M Acetic acid (HOAc) - 250 mL
6.00 M Hydrochloric acid (HCl) - 5 mL
Buffers, pH 4 and pH 10 - 10 mL
Wash bottle with deionized water
This experiment may require software and an interface for data collection.
