Question

HELP SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Read the following chemical equations.

Answer 1

Answer:

I is oxidized in reaction 1 and Cl2 is reduced in reaction 2.

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Consider the following reactions.

1 =    2KI  + H₂O₂    →       2KOH + 1₂

In this reaction the oxidation state of iodine is -1 on left hand side and 0 on right hand side which means it lost the electron and gets oxidized.

2=      Cl₂ + H₂       →       2HCl

In this reaction the oxidation state of chlorine on left hand side is 0 while on right hand side its -1 thus it gets reduced.
