Galvanic Cells - Questions
The Galvanic Cells Concept Builder is comprised of 24 questions organized into 12 Question Groups and spread across three difficulty levels. Each question requires the same task - completing the cell diagram for a galvanic cell.
Here is the breakdown of the difficulty levels:
- Apprentice Difficulty Level: Question Groups 1-4 ... Students are given contents of each half-cell and the balanced equation for the redox reaction. They must identify the half-equations, the anode and the cathode, and the direction of electron flow.
- Master Difficulty Level: Question Groups 5-8 ... Students are given contents of each half-cell and the balanced equation for the redox reaction. They must identify the half-equations, the anode and the cathode, the direction of electron flow, and the direction of positive/negative ion flow.
- Wizard Difficulty Level: Question Groups 9-12 ... Students are given contents of each half-cell and the balanced equation for the redox reaction. They must identify the half-equations, the anode and the cathode, the direction of electron flow, and the direction of positive/negative ion flow. Reactions are slightly more complex than the Master Level.
The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which difficulty levels are most appropriate for their classes. Alternatively, teachers can do the
