What is the purpose of a cell?
|
transform chemical energy into electrical energy
|
|
|
What are the three parts of a cell?
|
electrode, electrolyte, container
|
|
|
What is the purpose of each of the three parts of a cell?
|
-electrodes are the current conductors of the cell
-electrolyte is the solution that acts upon the electrodes -container holds the electrolyte and provides a means of mounting the electrodes |
|
|
What are the two types of cells?
|
Primary and secondary.
|
|
|
What is the main difference between the two types of cells?
|
The secondary cell can be restored to its original condition by an electric current. The primary cell
cannot. |
|
|
What is electrochemical action?
|
The process of converting chemical energy into electrical energy.
|
|
|
What is another name for the (a) positive electrode, and the (b) negative electrode?
|
anode, cathode
|
|
|
In the primary cell, why are negative ions attracted to the negative terminal of the cell?
|
The positive charge caused by electrons leaving the negative electrode attracts the negative ions.
|
|
|
How do electrons get from the negative electrode to the positive electrode?
|
By current flow through the load.
|
|
|
What causes the negative electrode to be eaten away?
|
The chemical action between the negative electrode and the electrolyte.
