Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Acid Base Titration
Use a pH sensor and drop counter to determine the molar concentration of a strong acid solution by titrating measured volumes with a strong base of known concentration.
Students determine the molar concentration of a strong acid solution by titrating measured volumes with a strong base of known concentration.
Note: Use the sodium hydroxide solution students determined the concentration of in the “Standardizing a Solution of Sodium Hydroxide” activity.
Students gain experience conducting the following procedures:
- Performing a titration and using the equivalence point volume of the titrant to calculate the concentration of the analyte.
- Calibrating a pH sensor and drop counter.
Sensors / Equipment Used:
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
Is a professional drop counter that allows students to capture detailed titration data. For use with PASPORT Interfaces.
