Electrons are transferred between Ions, during a redox reaction. The element losing, donating electrons is oxidized, and the element gaining/accepting electrons is reduced.
2Fe3+ + ➡️2Fe2+ Sn4+
Reduced: Fe Oxidized: Sn
Reduced:Mg Oxidized: Br
Reduced: Cl Oxidized: K
What is an oxidation-reduction reaction?
Oxidation involves an increase in oxidation numbers,while reduction involves a decrease in oxidation number. Usually the change in oxidation number is associated with a gain or loss of electrons, but there are some redox reactions that didn't involve electron transfer.
What is an oxidizing agent?
An oxidizing agent is the element or compound in an oxidation-reduction reaction that accepts an electron from another species. Because the oxidizing agent is gaining electrons, it is said to have been reduced.
What is an reducing agent?
A reducing agent is an element or compound that loses an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized.
What is an oxidation number?
Oxidation number is an number assigned to an element in chemical combination that represents the number of electrons lost by an atom of that element in the compound.
How is an oxidation number used in redox (oxidation/reduction) reaction?
Oxidation states simplified the whole process at working out what is being oxidized what is being reduced in redox reactions.
Explain what happens to electrons in redox reactions.
Electrons are transferred between ions during a redox reaction. The element losing/donating electrons is oxidized, and the element gaining/accepting electrons is reduced.
