Chemical Reaction Quizzes & Trivia

Below is an Oxidation and reduction reactions quiz trivia. Oxidation is the process where electrons are lost while reduction is the transfer of electrons between substances. Oxygen is either lost or gained in the reactions. In this quiz you will test out what you know about different compounds and substances and what happens when they undergo this process. Do give it a shot and see how well you do!


Questions and Answers
  • 1. 
    The terms Oxidation and Reduction both have direct polar opposite definitions.  what is each term defined as?
    • A. 

      Oxidation- the loss of electrons by atom or ion/ the gain of oxygen, Reduction- the loss of oxygen/ the gain of said electrons.

    • B. 

      Oxidation- the gain of electrons by an atom or ion/ loss of oxygen, Reduction- the gain of oxygen/ the loss of electrons by atom or ion.

    • C. 

      Oxidation- something having to do with oxide, i don't care -__- Reduction- something's being reduced, but i don't know what.

  • 2. 
    Can oxidation and reduction occur without one another? 
    • A. 

      They are interdependent

    • B. 

      They are not interdependent.

  • 3. 
    What, in simplified terms, does Redox mean?
    • A. 

      Its a combination of Reduction and Oxidation, when one occurs, the other does not.

    • B. 

      It is not a combination of reduction and oxidation , when one occurs, the other must occur as well.

    • C. 

      Its a combo of both REDuction and OXidation. one reaction cannot occur without the other.

  • 4. 
    What does LEO say GER stand for?
    • A. 

      LEO- Loss of Electrons is Oxygen, GER- Gain of Electrons is Red

    • B. 

      LEO- Loss of Elections is Oxidation, GER- Gain of Electrons is Reduction

    • C. 

      LEO- Loss of Electrons is Oxidation, GER- Gain of Electrons is Reduction
