Electrochemical series Flashcards
1
Q
What’s the electrochemical series?
A
basically just a list of standard electrode potentials for different half cells.
2
Q
For more NEGATIVE ELECTRODE POTETNIALS:
A
Right hand side substances are more easily oxidised
left hand substances are more stable
3
Q
For more POSITIVE ELECTRODE POTENTIALS:
A
left hand side is more easily reduced
right hand side substances are more stable
4
Q
equation:
A
E reduced - E oxidised
5
Q
when drawing an electrochemical cell, what do the 2 double vertical lines represent?
A
salt bridge
- reduced forms go on the ends, oxidised forms go in the middle
6
Q
MORE NEGATIVE= ?
A
OXIDISED
7
Q
When predicting if a metal can react with aqueous ions of another metal….
A
THE MORE NEGATIVE EQUATION FLIPS
THE POSITIVE ONE STAYS THE SAME
reaction is feasible if the:
reduced-oxidised = positive
eg. +0.34-(-0.76) = +1.10V
