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:
- Preparing three buffer solutions using different concentrations of acetic acid.
- Testing the buffering capacity of the three buffers by adding HCl.
- Calculating the predicted and actual buffer capacity of the three buffer solutions.
- Comparing the buffer capacity and buffering effect of the three buffer solutions and water.
Sensors / Equipment Used:
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
