Reduction Potential - Questions
The Reduction Potential Concept Builder is comprised of 36 questions organized into 12 Question Groups and spread across three activities. The tasks required by the questions vary per activity.
Here is the breakdown of the activities:
- Ranking Tasks - Oxidizing Agents: Question Groups 1-3 ... Using a provided Reduction Potential table, rank three different oxidizing agents according to their strength.
- Ranking Tasks - Reducing Agents: Question Groups 4-6 ... Using a provided Reduction Potential table, rank three different reducing agents according to their strength.
- Agents for Hire: Question Groups 7-12 ... Identify those substances that are capable of oxidizing or reducing another substance.
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
Concept Builder to gain a feel for the student experience.
