cava chem 303 5.10 Redox Reactions

QuestionAnswer
In REDUCTION, the CHARGE of something is [-ed]. In REDUCTION, the CHARGE of something is REDUCED.
Electrons have a [...] charge. Electrons have a negative charge.
[-ing] an electron will lower, or REDUCE the charge because electrons have negative charges. ADDING an electron will lower, or REDUCE the charge because electrons have negative charges.
[-ing] an electron will INCREASE the charge because subtracting a negative is like adding a positive (eliminating debts increases your net worth) REMOVING an electron will INCREASE the charge because subtracting a negative is like adding a positive (eliminating debts increases your net worth)
In a REDUCTION, something [...] an electron (or more) In a REDUCTION, something GAINS an electron (or more)
You might think that INCREASION would be the opposite of REDUCTION, but no, we call the opposite of reduction [...]. You might think that INCREASION would be the opposite of REDUCTION, but no, we call the opposite of reduction OXIDATION.
Increasing the charge of something (by taking away an electron or more) is called OXIDATION because the first such reactions that we studied all involved [...]. Once again, we’re stuck with a dumb name in chemistry for stupid historical reasons. Increasing the charge of something (by taking away an electron or more) is called OXIDATION because the first such reactions that we studied all involved oxygen. Once again, we’re stuck with a dumb name in chemistry for stupid historical reasons.
OXIDATION is when you [...] the charge of something (by taking away one or more electrons) OXIDATION is when you increase the charge of something (by taking away one or more electrons)
Here’s how to remember which is which: [...] is where the charge is reduced. Simple right? Think of that one first. [...] is the opposite (the charge is increased). Here’s how to remember which is which: Reduction is where the charge is reduced. Simple right? Think of that one first. Oxidation is the opposite (the charge is increased).
OXIDATION and REDUCTION always happen together (somebody loses an electron to someone else); so chemists call such reactions ‘[...]’ reaction for short. OXIDATION and REDUCTION always happen together (somebody loses an electron to someone else); so chemists call such reactions ‘redox’ reaction for short.
OXIDATION reactions do NOT always involve [...] (that’s part of the old definition that we don’t use anymore… I wish they never brought it up!) OXIDATION reactions do NOT always involve oxygen (that’s part of the old definition that we don’t use anymore… I wish they never brought it up!)
A chemical that gives electrons to another ([-ing] the others charge) is called a [-ing] agent. A chemical that gives electrons to another (reducing the others charge) is called a reducing agent.
A chemical that takes electrons from another (increasing the others charge) is called an [-ing] agent. A chemical that takes electrons from another (increasing the others charge) is called an oxidizing agent.
An [...] number is a number, negative or positive, that indicates an atom's capacity for oxidation or reduction. An oxidation number is a number, negative or positive, that indicates an atom's capacity for oxidation or reduction.
There are many complicated rules for assigning oxidation numbers and you are [...] responsible for memorizing them. Just know that they exist. There are many complicated rules for assigning oxidation numbers and you are NOT responsible for memorizing them. Just know that they exist.
Oxidation numbers are sometimes helpful when [-ing] chemical reactions. Oxidation numbers are sometimes helpful when balancing chemical reactions.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
