Electrochemistry Flashcards
Electrons on the right indicate…
oxidation
Electrons on the left indicate…
reduction
Reduction occurs at the…
Galvanic cell
Cathode
red cat!
Oxidation occurs at the…
Galvanic cell
Anode
an ox!
A higher standard potential corresponds to a ___ tendency to be reduced
higher
A lower standard potential corresponds to a ___ tendency to be reduced
lower
What happens if a half-reaction is used for oxidation?
It is flipped and so is the value of the standard potential
What is the formula to find the total cell potential?
E(cell) = E(cat) - E(Ano)
How is a galvanic cell set up?
anode | oxidized species || reduced species | cathode
Do oxidation numbers increase or decrease towards the center of a galvanic cell?
increase
Do you need to flip the anode potential when calculating E(cell)?
No!
What is Faraday’s law using moles?
Q = n * F
