WACE Chemistry — Unit 3
Electrochemical Series — Flashcards & Quiz
The electrochemical series ranks half-reactions by their standard reduction potential (E°), and WACE Chemistry Year 12 Unit 3 uses it to predict redox reaction direction, calculate cell EMF, and identify the strongest oxidant and reductant. The series is your lookup table for every galvanic cell calculation.
Sample Flashcards
Q1: How does the electrochemical series predict spontaneous reactions?
Lists half-reactions by E°. Spontaneous if the oxidising agent has MORE POSITIVE E° than the reducing agent. More active metals displace less active ones from solution.
Sample Quiz Questions
Q1: A more active metal can displace a less active metal from solution.
Answer: TRUE
The more active metal oxidises, reducing the less active metal's ions.
