Oxidation-Reduction Flashcards
(16 cards)
A common type of chemical reaction involves the transfer of electrons from one element to another.
Redox Reaction or Oxidation-Reduction Reactions
When iron rusts, methane and wood burn, and a battery generates electricity, one element gains electrons and another loses them. These reactions involve:
oxidation and reduction.
It is the loss of electrons from an atom.
Oxidation
It is the gain of electrons by an atom.
Reduction
Oxidation and reduction are opposite processes, and both occur together in a single reaction called an:
oxidation- reduction or redox reaction
A _____ always has two components - one that is oxidized and one that is reduced
redox reaction
It results in the gain of oxygen atoms or the loss of hydrogen atoms.
Oxidation
It results in the loss of oxygen atoms or the gain of hydrogen atoms.
Reduction
A compound that oxidizes another compound is called an ___.
oxidizing agent
An/A ______ gains electrons, so it is reduced.
oxidizing agent
A compound that reduces another compound is called a ____.
reducing agent
A _____ loses electrons, so it is oxidized.
reducing agent
When considering neutral atoms:
metals lose electrons
nonmetals gain electrons
When considering ions:
cations tend to gain electrons
anions tend to lose electrons
A ___ is a small electrical device implanted in an individual’s chest and used to maintain an adequate heart rate.
pacemaker
A pacemaker contains a small, long-lasting battery that generates an electrical impulse by a ___.
redox reaction
