| [-ic] cells produce electricity. | Voltaic (or Galvanic) cells produce electricity.
🗑

| Another name for a voltaic cell is a [G-] cell. | Another name for a voltaic cell is a Galvanic cell.
🗑
|

| Voltaic/Galvanic cells produce electricity from [...] chemical reactions. | Voltaic/Galvanic cells produce electricity from spontaneous chemical reactions.
🗑
|

| In a voltaic cell, the [...] from the two solution must move back and forth through a 'salt bridge'. | In a voltaic cell, the ions from the two solution must move back and forth through a 'salt bridge'.
🗑

| MEMORIZE THIS: Oxidation occurs at the [-ode]. | MEMORIZE THIS: Oxidation occurs at the anode.
🗑
|
||||
| Reduction occurs at the [-ode]. | Reduction occurs at the cathode.
🗑
|
||||
| The Anode is the name for the metal where [...] happens. | The Anode is the name for the metal where oxidation happens.
🗑
|
||||
| The Cathode is the name for the metal where [...] happens. | The Cathode is the name for the metal where reduction happens.
🗑
|
||||
| Anode and Cathode sound like anion and cation, so you'll be tempted to think that the anode is '[...]'... DO NOT DO THIS! This is not always the case! Just memorize that Anode and Oxidation go together. | Anode and Cathode sound like anion and cation, so you'll be tempted to think that the anode is 'negative'... DO NOT DO THIS! This is not always the case! Just memorize that Anode and Oxidation go together.
🗑
|
||||
| Anode and Oxidation both start with [...[; that will help you remember that they go together. | Anode and Oxidation both start with vowels; that will help you remember that they go together.
🗑
|
||||
| Cathode and Reduction both start with [...]; that will help you remember that they go together. | Cathode and Reduction both start with consonants; that will help you remember that they go together.
🗑
|
||||
| In a voltaic cell, electrons will flow from the [...] to the [...] if you connect them with a wire. | In a voltaic cell, electrons will flow from the anode to the cathode if you connect them with a wire.
🗑
|
||||
| Electrons always flow out of the [...] (the site of oxidation). | Electrons always flow out of the anode (the site of oxidation).
🗑
|
||||
| Oxidation and Out both start with O. This will help you remember that electrons flow out of the site of [...]. | Oxidation and Out both start with O. This will help you remember that electrons flow out of the site of oxidation.
🗑
|

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
