Featured in PASCO’s Chemistry through Inquiry Teacher Guide
Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.
Use a drop counter and pH sensor to to determine the concentration of a
hydrochloric acid solution and the concentration of an acetic acid solution by titration.
Use a titration to determine the concentration of a hydrochloric acid solution and the concentration of an acetic acid solution. Through this investigation, students:
Students conduct the following procedures:
Acetic acid solution - 10 mL
Beaker, 250-mL - 2
Beaker, 50-mL - 2
Graduated cylinder, 100-mL
Volumetric pipet or graduated cylinder, 10-mL
Wash bottle filled with distilled (deionized) water
Buffer solution, pH 4 - 25 mL
Buffer solution, pH 10 - 25 mL
Distilled (deionized) water - 200 mL
Hydrochloric acid solution (~0.1 M) - 10 mL
Acetic acid solution (~0.1 M) - 10 mL
Standardized sodium hydroxide solution (~0.1 M) - 120 mL
This experiment may require software and an interface for data collection.
