18-3: Half Reactions Flashcards
(5 cards)
1
Q
What is reduction?
A
The gain of electrons
2
Q
When writing a half reaction for reductions, where should the electron(s) be placed?
A
To the left of the arrow.
3
Q
What is oxidation?
A
The loss of electrons
4
Q
When writing a half reaction for oxidations, where should the electro(s) be placed?
A
To the right of the arrow.
5
Q
How do you create the overall balanced reaction for oxidation reduction reactions?
A
Make the oxidation and reduction half reaction.
Make sure the number of electrons in both half reactions are equal.
Combine the equations.
