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.
An Acid Base Titration
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:
- Differentiate between concentration and strength of acids and bases.
- Perform neutralization reactions.
- Describe and explain the shape of a titration curve.
Students conduct the following procedures:
- Perform a strong acid–strong base titration.
- Perform a weak acid–strong base titration.
- Calculate the concentration of an unknown hydrochloric acid solution and an unknown acetic acid solution using collected data and stoichiometric calculations.
