Required Practical 8 Flashcards
Measuring the EMF of an electrochemical cell.
1
Q
Describe a method for measuring the EMF of a zinc-copper electrochemical cell.
A
2
Q
What is a salt bridge?
What is it made of and what is one of its key properties?
Why isn’t a wire used instead of a salt bridge?
A
3
Q
If one or both of the half-cells do not contain a conducting metal, what metal can you insert to use as an electrode?
Why does it work as an electrode?
A
- If one or both of the half cells do not contain a conducting metal, we must use an inert platinum electrode.
- A platinum electrode is used because it is unreactive and can conduct electricity.
