Redox Flashcards
Outline the activity series
More reactive metals in the activity series displace less reactive metals in solutions or from their oxides
The more reactive metal acts as a reducing agent, and is oxidized
Outline the process and purpose of redox titrations
Titrations are used to determine the concentration of a solution by titrating it with a solution of known concentration
Oxidizing agent is titrated against reducing agent
What do voltaic (galvanic) cells do
Generate electricity from spontaneous redox equations
What is a salt bridge and why is it used
It is a piece of filter paper saturated with an inert electrolyte
it allows for the movement of ions between the solutions
What is the positive electrode in voltaic cells?
What is the negative electrode in voltaic cells?
Positive : Cathode
Negative: Anode
on which electrode does reduction occur?
On which electrode does oxidation occur?
Reduction always occurs on the cathode
Oxidation always occurs on the anode
What is the flow of electrons like in voltaic cells?
Which electrode is the more reactive metal?
From the anode to the cathode
The anode, which is negative
What is electrolysis?
The process in which ionic compounds are separated into atoms using electricity
What is the positive electrode in electrolysis?
What is the negative electrode?
Anode
Cathode
What is the movement of electrons like in electrolytic cells?
From the anode to the cathode
