it talks about redox reaction

1. Oxidation and
Reduction
Reactions
Glaiza V. Abucay

2. oxidation–reduction reaction
◍ Also known as REDOX reaction
◍ A reaction that involves the transfer of electrons
between chemical species (the atoms, ions, or
molecules involved in the reaction).
◍ In any reaction, oxidation and reduction always
work simultaneously

3. ◍ Redox reactions are all around us: the
burning of fuels, the corrosion of metals,
and even the processes of photosynthesis
and cellular respiration involve oxidation
and reduction.

4. OXIDATION
◍ The process when an atom,
molecule, or an ion loses one or
more number of electrons in a
chemical reaction.

5. REDUCTION
◍ The process when an atom,
molecule, or an ion gains one or
more number of electrons in a
chemical reaction.

OXIDATION is LOSS REDUCTION is GAIN

7. In determining the oxidation state of an atom,
there are seven guidelines to follow:
1. The oxidation state of an individual atom is 0.
2. The total oxidation state of all atoms in: a neutral
species is 0 and in an ion is equal to the ion charge.
3. Group 1 metals have an oxidation state of +1 and
Group 2 an oxidation state of +2

8. 4. The oxidation state of fluorine is -1 in compounds
5. Hydrogen generally has an oxidation state of +1 in
compounds
6. Oxygen generally has an oxidation state of -2 in
compounds
7. In binary metal compounds, Group 17 elements have an
oxidation state of -1, Group 16 elements of -2, and Group 15
elements of -3.

Na + Cl Na+Cl-
OXIDATION
REDUCTION
Na is oxidized. It loses an electron
Cl is reduced. It gains an electron.
