Activity Series
Metals higher on the activity series are more likely to do this.
What is oxidize?
To create a strong voltaic cell, you should pair metals with a small or large difference in reactivity?
What is a large difference?
A positive cell potential means the reaction is this.
What is spontaneous?
Rusting is a common example of this process.
What is corrosion?
Painting metal helps prevent corrosion by blocking these two things.
What are oxygen and water?
Between Cu and Zn, this metal is more reactive.
What is Zn?
In a Zn-Cu voltaic cell, zinc serves as this electrode.
What is the anode?
The unit used for measuring cell potential.
What is volts?
Iron rusts when exposed to oxygen and this substance.
What is water?
Coating iron with zinc is called this.
What is galvanization?
A metal higher on the activity series can do this to ions of a lower metal.
What is displace them from solution?
Electrons travel through the wire in this direction.
What is from anode to cathode?
Reduction always occurs at this electrode.
What is the cathode?
Salt water speeds up corrosion because it increases this property.
What is conductivity?
A more reactive metal used to protect iron is called this.
What is a sacrificial anode?
This metal would oxidize more easily: Mg or Ag.
What is Mg?
This device allows ions to flow and keeps charges balanced between half-cells.
What is a salt bridge?
If reactant concentration increases, cell potential generally does this.
What is increase?
Corrosion involves the oxidation of this type of material.
What is metal?
This metal in stainless steel helps resist corrosion.
What is chromium?
The farther apart two metals are on the activity series, the cell potential generally becomes this.
What is larger?
Which pair would create the greatest cell potential: Mg/Cu or Ag/Cu?
What is Mg/Cu?
A voltaic cell stops working when this happens to the reactants.
What is they are used up or equilibrium is reached?
Iron acts as the anode during rusting, meaning it undergoes this process.
What is oxidation?
In cathodic protection, the protected metal becomes this electrode.
What is the cathode?
