Voltaic cell
what is an Oxidation state?
The apparent charge on atoms or ions
What is half reaction?
It shows the oxidation or reduction portion of a redox reaction
What is a salt bridge used for?
A path of ions to travel between the cathode and anode.
What is one similarities both cell types have?
Both involved redox reactions
What happens when an Oxidation state goes up?
The species gets more positive
What happens when half reactions go through oxidation?
They lose electrons.
