Teacher manual for AP* and Advanced Chemistry labs. Has both the printed version and a flash drive with teacher tips, a PDF of teacher version and editable Word student version.
Reactions that occur without outside intervention are said to occur spontaneously. Non-spontaneous reactions can occur if some outside factor provides enough energy. Electrolysis is the process of using electricity to force a non-spontaneous reaction to occur. Electrolysis can be used to separate pure metals from their ore and plate metals onto surfaces.
How can you make a non-spontaneous reaction do useful things?
By electrolyzing a variety of aqueous solutions, students determine a relationship between current, electric charge, and quantity of electrons.
The student can make qualitative or quantitative predictions about galvanic or electrolytic reactions based on half-cell reactions and potentials and/or Faraday's laws.
LO 3.13 / The student can analyze data regarding galvanic or electrolytic cells to identify the properties of the underlying redox reactions.
Sensors / Equipment Used:
Allows students to safely measure voltage and current simultaneously without overloading the sensor. For use with PASPORT Interfaces.
The Associated Bundle:
Contains the sensors and probes needed to perform all 17 experiments in the Advanced Chemistry Teacher Guide and all 25 labs in the Chemistry through Inquiry Guide.
