Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Standardize Sodium Hydroxide
Use a pH sensor and drop counter to determine the concentration of a sodium hydroxide solution by titrating it with a standard solution of known concentration.
Students determine the concentration of a sodium hydroxide solution by titrating it with a standard solution of known concentration.
Students gain experience conducting the following procedures:
- Calibrating a pH sensor and a drop counter.
- Preparing a titrant solution.
- Preparing a standard solution.
- Performing a titration and using the results to calculate the concentration of the titrant.
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.
