Chapter 19 Flashcards
1
Q
what is an oxidation half-reaction
A
a gain of electrons corresponding to an increase in the oxidation number
2
Q
What is a reduction half-reaction
A
a loss of electrons to decrease the oxidation number (reduction of the oxidation number)
3
Q
how do you balance Redox reactions
A
make sure both sides have the same charge by adding electrons
4
Q
what happens at the anode
A
oxidation; the charge of solution increases
5
Q
what happens at the cathode
A
reduction; the charge of solution decreases
6
Q
How do you find the overall cell potential
A
cell potential cathode + cell potential anode
